Can anybody I.D. this bracket? Im guessing G body?

I'm pretty sure that same bracket was on a 1974 455 I recently had. So I'd lean more towards the 73-77 vintage than the G body.

Correct. The G-body cars use the aluminum bracket that bolts to the front of the head and a steel bracket with tubular braces.

I'm pretty sure this fits 1972 engines with AC. Here's a page from the '72 assembly manual and some pics:

Thx guys, now Im really confused

Why? These brackets spanned multiple model years.

I just want to know exactly what years in case someone needs this. If it fits 72 and also 73-77 would it be safe to say it also fits 70? so 70-77 or even earlier perhaps?

Contrary to popular belief, the brackets are not the same from 70 to 72. The alternator brackets for A/C cars are the the same for 1968-71. 72 was the first year for the style you have - and it was used through the 1980 model year.

Apparently this individual has some familiarity w/ this bracket & brace. The parts numbers align w/ what is described in the ASM.
