In case it was not clear from my explanation ,the washers and the bolts are unrelated. Most 66 production and up Shelby's used the made to Ford specifications heavy duty adjustable shock designed for harsh road conditions. It was not considered a standard Mustang shock.

so - for education purpose:
I thought that the "shock tower washers" were on '65 and '66 GT 350's as the Koni Shocks were somewhat less wide than the standard shocks and thus the washers... AND the longer bolts to hold the shocks were added as well..  is this correct?

The '67's having standard shocks would need neither...  or were they "supposed" to have washers on the tower caps without the longer bolts?

BTW - my '67 has neither the washers or the longer bolts...

The reinforced upper brackets were not Shelby unique. It was part of something called a export package. The heavy duty items in the package were first designed for rougher roads encountered in Europe and other places hence export package stuck. Heavy duty adjustable shocks and a one piece stronger firewall brace were also part of the package . The Koni shocks evolved to another heavy duty adjustable shock mfg starting in early 1966. That new shock was one that Ford had control of the design and most likely cost too.  The different bolts for the Koni's was in response to a smaller surface area on the Koni shock mounting cross bar. The special bolts had a larger head to bridge the smaller surface area of the cross bar mounting.  Different bolts were not needed when used with the different mfg shocks that Ford had contracted to be built to their specifications by Gabriel . The relative thin metal of the upper shock bracket was prone to fatigue and cracking under harsh conditions unless reinforced . The one piece upper firewall brace commonly refereed to as a export brace was made of thick steel compared to the the two separate sheet metal formed stock firewall braces on regular Mustangs.The one piece thick steel brace did not allow as much flex in the front end on rough roads as the stock braces. All of these export package components had value in road racing handling as well which is why they were chosen as part of the specified design of 65-70 Shelby's     
I thought I would add before someone mentions it is that although the heavy duty shock and reinforced upper shock bracket were used the 69/70 did not incorporate the one piece firewall brace in the Shelby specified design.

If it was a cool or interesting mistake I could see keeping the inferior part. The use of the regular upper shock bracket makes a 67 Shelby less then another 67 Shelby that has the correct stronger part like the car was designed to have IMO.
Bob, My guess is that I just flat overlooked it. I was only about 28 when I started the process. I don't remember them on the car. Back then the references just weren't out there. There are SO many early books that are the cause of the rumors and false information.
I guess at some juncture I'll correct the issue.

They are easy to make . Someone else asked about what is required.  I will get measurements for the washers later this week and post. AMK sells the washers. They are tack welded typically in 3 spots. two on each side and one in the back (back is opposite of were the shock shaft comes up through).

Hello Bob,

Do you have that AMK part number for the washers that are correct? Trying to get my AMK order together and I could sure use these!
Many thanks!!

If you have access to engine head parts, FE 390/428 rocker arm shaft stand retaining bolt washers would be correct, or very close. I have made proper looking tower shock caps using these washers.

Don't forget they are cut in a D shape.

You can cut them before with a cut off saw or after they are tac welded on then use the edge as a guide and cut them off.

Do the clipped washers as on the power steering frame bracket work?

    Mig weld , high heat , sloppy because you were in a hurry and didn't care.
'65 and '66 one "tack" on each outside. The FE rocker stand washer is what was used, I have it on good authority.
