What size bolts are used to mount the fronr calipers on a 1980 vette. I need the thread size and length. I know they use lock washers, do they use any spacers?
Thanks...Len
I 'think' they are 7/16-20 x 1-1/4"... make sure not too long.
get grade 8 coated. pay close attention to the thread length as you want to make sure it comes close enough to the head.
also, avoid using split lock washers. they are junk and do more damage to the bolt head and bracket if they grab. i use a flat washer and Loctite. serrated Bellville (expensive) or internal star + flat washers is another way.
