thinkin 3/8sx18  3/4 long    or are they metric already ?     fenders were 1/4 x20 3/4 long

I thought they would be standard, prolly 3/8

85 cab has metric body bolts on them.

This was a big headache when putting the 86 cab on my '77.

usually M10x 1.50 when theyre metric... but you can run a std 3/8 tap through it and retap it to standard....
