My Mach 1 was built early and has these acorn nuts retaining the hood molding. AMK-F1196.
The 70 Mustang Body Assembly Manual (AM0031 [pg 49) specifies 45277-S36 for the taillight panel. I assume that's what is in the AMK kit (my previous stand, you really don't know what you are getting in their kits). The hood molding is 384102-S100 (Same book, pg 25) but the two nuts are different. The only things that are the same is the thread, 8-32, and name, acorn nut. They will work, but -
