Hi Jcl67,
I own 67412F2A01183 which was completed the same day at SJ and is of the same DSO group. Mine is mostly original, including original paint, etc. I know what I have messed with and most of original owner mods. I would be glad to help.
Thanks, that helps a bit.
#01255 a 412F package (GT500 auto WITH emissions).
The basic knockdown unit was built at Ford’s San Jose factory on 1/26/67. There were several different DSO groups built on that day with about 38 units destined for Shelby American to be completed. While they were all 500s, a few were automatic without emissions, and about half were 4-speeds also without emissions.
Your cars DSO group 84-2566 contained only 32 cars built over three days; 1/26, 1/27, and 1/30.
It might be best to look at the cars in that DSO group to match component parts against...such as 1183 who is right here to help!
