A later '66 would have had a cast iron main case and tailshaft housing. Close ratio gears, but a T10, not a toploader. Also no VIN stamping.
Different 2nd and 3rd gear ratios than a "production " K code T-10.
t-10, not toploader, a plus if it's got the nickel gears. phred

Thanks Brant
What was the time line, in vin numbers, of the change over from aluminum case and tail shaft to iron tall shaft to all iron transmission?
Thanks,

In getting these in for rebuild Ive seen alloy T10s to around serial number 1000 or so. Ive never been able to document an original untouched car that came from SA with a cast iron Tailshaft. Talking to some of the SA people years back they knew there was an issue and they thought the tails were replaced by the dealers at no charge if they broke. Ive weld repaired many especially the longer T10L versions. On another note. Ive got SA catalogs showing the T10M with cast iron tails being sold over the counter

Did they change over at some point to all iron cases during 1966 production.
My experience is the same as Jim's. The switch was made around vin 1,000 but there is some back and forth overlap. '66 production units were all aluminum or all iron. none were half and half . The only cars to have the half and half transmissions were the '67 T/A coupes. This was based on the amount of tailshaft housing failure in race conditions in previous years. NO other production SAI vehicle used that transmission. The Transmission was also used for the '68 T/A season but there were no "customer cars" sold that year. "I" was told the original P.O. was for 100 half and half transmissions. The rest not used in race cars were sold out of the catalog as Jim mentioned until all were gone. I was also told that "warranty" repairs were only authorized to use the cast iron tailshaft housing when a repair was needed. This came from the late Ray Wolfe . One of his titles was Service Manager at High Performance Motors when it was operating. When I used to buy parts from him in the late '60s and 70's he had about ten NOS half and half T-10s for sale.
for what it's worth, 1122 has the iron trans case/tail and the good gears. original except the shift forks. phred
usapony,
There were no "later" 1966 4 speed cars manufactured at SAI. Last number 4 speed is 6S612.

Interesting, 1114 has an aluminum case T-10 with a cast iron tailshaft. It sounds like the tailshaft was probably switched out based on Jim & Randy's comments above. Thanks to Joe Bolus, it has been reunited with the car.

Actually, 4-speed 66 GT350's were produced throughout 66 production, you might be thinking of factory 4-speed Hertz cars...

Dave,
You are VERY right, I was thinking of the Hertz cars. My bad!
Hey guys, not sure if this is the place to ask. Is there somewhere to find the breakdown of automatics/4 speeds for the '66's?

More interesting, 1134 has an aluminum case T-10 and a cast iron tailshaft. It would be nice to know if more cars in this range have the same setup. Coincidence or pattern?

6s1117 also had an iron tailshaft with the aluminum main case. I know ALL the owners, and that car came that way from el Paso Ford, and presumably from SA as well. It could've been been switched at the dealership before the car was sold to the 1st owner, I suppose, but not as far as the 1st owner knows. There was no warranty work done on the transmission after delivery, that much is known.

There have been many cases where dealers and their sales people were very hard on these cars. Blown engines, clutches , transmissions The tails and side covers were very fragile compared to iron versions. Ive had customers that broke out side covers and tail shafts just by power shifting. Try to find a 4 speed Hertz 66 that #1 has the original transmission #2 has one that hasn't been welded . We've probably been involved in the restoration of close to 100 of these all aluminum transmissions and Im guessing Ive weld repaired over 30%. Its always a treat to get one that the alloy case and tail or in good shape. The one trans that was a head scratcher was the one that was in 6S001. The case and tail were near perfect castings but the inside was just trashed. we had to replace virtually all the parts in side.
