Alternator overdrive pulley. will this one work
i have a 1986 trans am and was looking into getting an alternator overdrive pulley but was wondering on the shaft bore size as ive been seeing different sizes. I was looking into a march one, part number MCH-110-08 from summit, but would like to know the diameter size of the shaft so I get one that fits properly. or if the one I am looking at will work can someone please confirm to see if it will fit and work. thank you.

I think it should be the standard 17mm, so it should work.
That one on summit is made for the full serpentine belt system though. That's not what 1986 fbodies came with.

I use cv products pulleys they are super small for the small diameter crank hub drives. They do take only a small 3 rib belt though.

hmm I guess I cant find one that will work with my set up than. unless someone can point me to the right direction. I called and the guy said it would work so I ordered it. how shitty is that.
