Wouldn't you need two groove for the water? And single for ps? Do you need the brackets also? I have one complete extra set. (Corrected with the info from wes)

You are correct. Pulleys and brackets would be great...Thanks.
I also need exhaust manifolds if you have a set.
Please PM the price.

Re: WTB - pulley set for '72 Blazer

Okay, what I have is a complete setup but not the same....I think the extra pulley might be for an air pump? (4 for the crank)

Ps pulley 3925537 (maybe difference is press on vs bolt on?)
Wp pulley 3995646
Inner crank 3744043
Outer crank (cast iron two groove) 3923898
Brackets are a mix of cast and steel also...
Any confirmation on these wes? I believe them to be correct with a/c and swp (they were sold to me as)
