Bracket ID help
 

I have no idea what this is for, but pretty sure someone here know. Thanks in advance.

Alternator bracket on engine

Ralph, could you be a little more specific?

That’s tough, so many I got a bud who’s got a big box of brackets, wants me to,post on a forum for him ��*��

Looks more like an A/C compressor belt tensioner bracket. Would have been bolted to the intake. Sorry, no knowledge as to specific app or year.

P/S to A/C adjuster
 

This is a 77-81 SBC adjuster bracket. It bolts to the first exhaust manifold bolt and connects to the the main A/C bracket. The adjuster slot is for the P/S pump.

Much appreciated. Apparently it goes back to 71 as the first year.

No, GM used several different ones from 69-76, but never this style. I've dealt with "The Parts Guy" before, nice guy but his application years for many of the brackets he sells are incorrect.
