Hi Milton,
Take a look at Tony's AMK spreadsheet that I posted at the top of page 3. I've added listings for the "SS Wheel Moldings" for front and rear. On my two cars the fronts and rears are different. Here's what I purchased:
Front: Original 8-18 x 3/8 Pan head. AMK B-12057: 8-18 x 3/8 Pan head tapping screw, zinc (dark silver). Looks like the original except a slightly thinner head.
Rear: Original 8-18 x 3/8 Round washer head. AMK B-10063: 8-18 x 7/16 Round washer tapping screw, chrome on stainless.
I dug them out and compared them to the screws from our parts car. The fronts appear to be accurate, but with just a tad thinner head. The rears have a slightly larger head and are about 1/16" longer than the originals, but are as close as I could get from the AMK catalog. Pictures attached.
An FYI, these screws from the parts car appear to be the same as those from my other two 65s.
