Serpentine Bracket Bolts

[Clinscott]

So I recently sprang for a serpentine belt setup to put on my 75 K10. I got the brackets yesterday via EBAY. Brackets look good and appear to be from the 88-92ish truck style. Problem is there are no bolts whatsoever. I figure some where someone has done the homework and figured out what size bolts secure the brackets to the block and heads. Also what bolts I will need for the alternator and AC. It would be greatly appreciated. Thanks

Have you considered taking a few pics of your brackets mocked up in place where they belong and then going to a junk yard, finding the matching configuration and getting the bolts. My entire bracket and bolt set came from a junk yard.
