What pulleys for P/S and A/C
 

Lost my file or deleted my file with pics of what they look like. How many pulleys and how many grooves do I need?

Pretty sure you just need the one crankshaft pulley, and if you want both ps and ac, three grooves. Tough to find three groovers though. You might be able to get one made at a speed shop though pretty easy.

Ok thank you FMAP. I will start looking. So what goes in the three grooves. 1. Alternator/water pump. 2. A/C. 3. P/S ??

AZKen; I remember this post here...

it's GMCNUT's Kool Suburban with all the goodies your looking to add.

Per one of the last posts he mentions that the AC was a double groove with a bolt-on single groove for the AC.

I'm not sure if they all did it that way, but his was set up like that.

Here is a photo I have from an eBay listing of said lower pulley and also the upper and lower double groove pulleys from the archives.

Thank you everybody. I got the answer I was looking for.
