Wanted gm part #12558927
 

If anyone has one gathering dust, I'd like it. It's the correct ac/ps bracket to use on the 8.1L I'm swapping in my 97 crew cab. I can find all the other brackets, water pump, and balancer, but still looking for this. They used this setup in workhorse rv's and G series vans.
Thanks!

I just purchased a #12563068 from a C4500. It takes the ZF style PS Pump. I am doing a swap into a 79 Trans Am so I do not need the heavy duty steering pump so I am looking for the #12558927 so I can run the Saginaw style in mine. If I can find the smaller pump bracket I would be looking to get rid of the ZF style if you are interested.

The brackets are dependent on what they were installed in. If they were in a truck or SUV the alternator is on the drivers side and the a.c. compressor is on the lower passenger side. If you want to run a.c. at least for me there is not enough clearance. The brackets from the motorhomes, vans, and medium duty trucks move the alternator to the passenger side and the a.c. compressor on the upper driver side. The medium duty truck bracket that I have is designed for the ZF style pump. The motor home and van units typically have the Saginaw style pump. The big challenge on getting either bracket is GM has discontinued the part and most salvage yards do not inventory brackets so they are hard to find.

I may, let me check into how the bigger pump would fit my truck. I'm putting the 8.1L in my 97 cclb.

Let me know. I have everything i need on my end so i have a brand new #12563068 bracket.

I'm still checking, but I noticed Larry, the 8.1L swap guru, said the ZF pump wouldn't work in older trucks. I sent him a pm asking about the 88-98 trucks just in case. Seems like there's enough demand for these that someone would make a few lol.

I tried to by a bracket from that site before and they ended up canceling my order and refunding because it was a discontinued part. I had a local large truck repair shop find a NOS part on a dealer shelf for me and had to pay their markup and shipping to find the one I have. I replied to your PM. I apologize I did not have my email notifications turned on.

No problem, apparently I have mine turned off as well somehow. My zip code is 72315 so you can get the shipping cost figured and thanks!
