Jason,
Did you look in the Library under Mustang Hardware Spreadsheets for 64-66? The screw listed is 378428-S8, 5/16-18X3/4 flat head, Pozi drive. AMK sells a "similar" screw but I don't know the difference. If you are going in the general direction of Santa Clara this weekend, send me a PM and you can "take a look".
I'm the one that made the referral on your rear axle.

Ah, ok, that's where I was reading the Mustang Hardware Spreadsheet list incorrect, the S8 is the finish code, which is on the second page of the library, missed that. Thanks so much, I didn't think it was gold zinc, and of course someone was insisting on telling me it was supposed to be... Thanks as always for your help...
Also, unfortunately not going to have time this weekend to head to Santa Clara, going out of town with the lady
And thanks for the referral, still about 9 months out from the project... I'm happy though, everything is coming together nicely, it's nice just to be dealing with all these little small things at this point, like correct screws for my strikers
Thanks again,
Jason
