I have a 1984 k5 with the 6.2l Detroit diesel in it and I have a/c. When I got the truck the ps pump was shot and I had to replace it. The pulley was bent on it so I also had to replace that. The problem is that GM does not make the ps pulley for the blazers with the a/c anymore so I was forced to put on the single belt pulley on instead of the double. Does anybody know of any pulleys that would work for me? The diesels are scarce in the junkyards and I cannot find any aftermarket replacements anywhere. Thank you for your help!

 

I would expect any of the gasser pulley's would work.
