After reading the Sill Plate Emblem discussion for the 1967s it brings to mind what are the 1966 sill plate styles and how do the relate to Shelby numbers. I know there was past discussion about this but thats gone so here is the new question.
Thanks.

Thanks for posting the question. We need to slowly build the data base back. Along those same lines, it would be great if folks who have taken it upon themselves to reproduce parts for our cars repost the information as their time permits. I am sure it will be appreciated.

Inquiring minds want to know 1966 GT 350 sill plate emblems for 1966.
Here is what 1348 has on it presently. In 1980's I replaced the beat up sill plates with NOS Ford and Repo (?) Shelby emblems. I stored the originals in my garage but they went somewhere else. I could not find them when we moved. I noted the 1967 discussion was very informative about 1967 and hope similar information can be obtained here about the 1966 cars.

FYI you can get a better reproduction through Brant at Virginia . The race track CS is embossed on the original and also on the Scott Drake ones through Brant. They are not perfectly exact like original but a lot better then later NOS service or other reproduction that do not have the raised CS.
Will go through my files and pictures and repost what I posted (or close to ) last time showing the two styles I've found over the years.

(http://wasaac.org/temp/6S1757label.jpg)
As you can see the letters are different compared to the reproduction.
Here are some notes I made from the previous forum discussion on the topic sill plate emblems for 1965-66:
1965 GT350 – All had black Ford oval
1966 GT350 – 6s001 = black Ford oval
1966 GT350 – 6s002 to end = one-line label. Most were embossed, but late in production there may have been some original flat emblems. That change may have happened between 6S1769 and 6S2020.)
The double-line emblems appear to have been Ford factory service replacements.

Updated on 3/29/18. The info I posted above is not completely accurate. See reply #22 in this thread for better information.
Still going through pictures. Have them for about 50% of the cars in one form or another so taking some time.
Here is the picture of what was on the wife's car. Same picture I posted last time. Knowing Doug he never replaced them and what was in the car when I first road in it in 73
(http://www.concoursmustang.com/forum/gallery/10/6-210318043333.jpeg)
Two line version
Will post some pics of 6S373's which has original one line emblems and sill plates. Wasn't there a change over period from one to two line emblems? Not all the 66's had one line plates?
Cheers

Reproductions are very, very close if not exact. The letters may be a bit bolder or just appear to be due to the comparison between brand new and 50+ years of wear.

I've never seen a "two line" label on a '66 that I could absolutely verify as original.
The later '66s that I have seen, have the same "one line" label, but they have silk screened (flat, not raised) logo, lettering and border.

Have a fair number of examples (two lines) that are as easy to prove are originals as most of the single line examples IMHO. Good time to rehash this since additional information turns up all the time and this may benefit from a fresh look if we can do that.
Currently it appears there may be some problems with the idea that they were possibly service replacements only.
The challenge is that there is a high percentage of cars that have been restored in the past 50 years and of course those are always suspect in one way or another.
Think a discussion and a look will be good
To continue a focus on the two or dual line discussion. If it were a service replacement when would it have been made and available to the public?
And since it could be considered part of the discussion what are peoples thought on the additional (what looks similar to weatherstrip adhesive) glue often found holding any of the emblems in place?

Brant,
Thanks for posting the pic. Other than the bolder SAI font on the repro as you mentioned, the other thing I've noticed from pics is the repro edges appear slightly beveled. Is that correct or just an illusion?
Thanks,
Dave

It is more then a 50 year age patina difference. Don't get me wrong because I am glad to see the raised style sill plate emblem available but if you think that the letters are exact when you compare the genuine original to the reproduction I respectfully disagree. I know it is more then just me . I can tell from ten feet away . It frustrates me when the aftermarket gets one very close when they could have done a little more research or to a little more effort and gotten it exact.

Thanks added to the spreadsheet
Sorry been gone on a short trip but wanted to get back to this subject and not leave it hanging
I went through all my current pictures and notes then noted if the cars had been restored or possibly had their sill plates replaced. Also ignored rebodied cars and modified (race) cars.
One thing that popped up right away dismissed the likelihood IMHO of the two/dual line versions being service replacements since they (expanded the search) since if these were only service replacements why would Shelby make a new design just for replacements rather than copy something they already had art work for. And if they were service replacements made available after production (example 68) why are they not found on 65, 67 and 68's also). Haven't found any examples of them on other years which suggests that they were a factory variation applied during the production year. That doesn't add up IMHO
Since I was using pictures that focused on the sill plate labels and those that did not I did not have enough clear close ups to collect important data points as to smooth or those created with a relief design on the surface and will leave that discussion alone for this survey
With all this I created two charts. One that shows what appear to be original sill plate labels and one that included "restored" examples hoping that many owners/builders would have chosen to reuse or replace the sill plate labels with what they found or removed during disassembly
What surprised me is that many of the restored examples fell in line and supported what had been reflected in the "original" chart and suggest IMHO that both emblems were used at the same time during much of the production year.

(http://www.concoursmustang.com/forum/gallery/10/6-280318193659.jpeg)
To me the early period (pre #400) is still in question since only a single possibly original finding anchors that group and the same goes in the over 1900 area.
Production period from approx #400-#850 was small and no conclusion can be drawn for that period at this time.
Great info! Thanks a lot, Jeff.

I think that the word Brant was looking for here was "EMBOSSED". Embossed refers to a raised area..

The post made me dig out some really mint door sills from an original shelby.
Did 65 have the CS reversed to the other side?

I truly can't remember.
I agree with you, there are noticeable differences in repops.

John, 65 typically had the Ford sill plates. The 67 plates were two line and had a flat CS. Bob
Bob,
Could it be that the picture shown is reversed?
The CS on mine are originals and on the opposite side/end ?
I need to get my 67 out of its decades long sleep, and see what all I have in all the boxes, sill plates inc.

Yes a heat gun will soften the adhesive.
Tip of the day, heat gun works great. Heated up then used a utility knife blade to slide down the length behind the plate. Thanks Bob
I recently acquired this copy of an original design of the 66 GT 350 door sill plate tag. It was drawn by a Mr. Kerr who apparently worked under Peter Brock. It was signed off and approved by a young project manager named C. Cantwell. Chuck Cantwell signed off on it 7/6/65. It might be helpful to this conversation because it shows a lot of dimensions and even the raised areas that they designed into the plate. Under the material to be use section, it says "foil with adhesive backing". The sample in the lower left corner is smooth but I believe it was just a test sample.
Interesting piece. Thanks for sharing
Very cool. ;)

It might be helpful to this conversation because it shows a lot of dimensions and even the raised areas that they designed into the plate. Under the material to be use section, it says "foil with adhesive backing". The sample in the lower left corner is smooth but I believe it was just a test sample.
Thanks for sharing, this information helps makes sense of the two versions seen in the production run. The early (7/65) version was a more intricate and therefor more expensive then the later two line. This fits with how the later cars in 66 loose many of the 65 and earlier 66 features.
