Jeff are you saying that a 68 J code GT W/O AC would have the front springs marked with violet and yellow?
That was related to Tim M's post about what he found as his front spring colors/markings. But what I had not taken into consideration was body type - which was inserted in my post above.
Double checked and without consideration for body type yes the front springs on the buildsheet I have of a J code GT w/o AC does show Yellow and what looks to be a V. And V should indicate violet on that car. Now what we are missing in the mix is the body type.
Looking through my collection I found no 68 J code coupes with HD/GT suspension. Hope that clears things up a bit
It is interesting that the USA shocks were fine thread and the Canada were fine. So then I understand that most of the HD Autolite shock for GTs were USA made?
All that I have been able to find so far are C5 Autolites, I will keep looking. May be I'll get luck and find some USA made.
Sorry I wasn't clear enough, should have written (will correct) course (USA) and fine (Canada). Went back and added a little more to make it clearer to readers
Here is an example below - Sectioned buildsheet. Bottom left corner is what is left of the front spring color section. Guess I could have found a better example
According to the Buildsheets (its not common for them to list these on non-Shelbys) they show a number of C8ZF-H for the GT/HD suspension shocks. So that should give you some info to go on.
The difference I believe is based on where the car was built and in turn where that plant got the majority/or all of their supply from. From looking at allot of cars it appears San Jose Mustangs got the Made in USA shocks and in turn course threaded rear shocks. This came up years ago when a friend complained that MCA had approved some repo shocks (back in the old days when they did that sort of thing) and "they are all wrong" it was reported. It basically came down to we were use to seeing shocks in the west marked Made in USA and with course threads and the person reproducing the shocks choose a shock that was typical shock that was seen on cars in the eastern US.
Some home work was done and that was the conclusion that seemed to give logic to what had happened and the difference of opinion.
I believe that in Augusta you or Tim said that on the 68 Shelby that course threads were on the manual transmissions and the fine were on the automatics I think. Of course those were Gabriel shocks but why the difference in the threads?
Now we're getting a bit off topic bringing in Shelby's since they often but not always used different shocks on these cars. By 68 adjustable Gabriel's were being made at one of their Canadian plants rather than the US plant as they had done in 1966. In 68 - only the 4 speed KR's got a different non- adjustable. Instead a "regular" semi-gloss black non-adjustable Autolite shock.
On 68 KR 4 speed cars the build sheet simply calls out an Orange identification mark while the non-4 speeds have a stamping number identifier in that box indicating the adjustable style
