Title: ???? R4 ac compressor brackets ????
Post by: sireal on August 14, 2010, 09:19:54 pm

Does anyone here happen to have pictures of the brackets on the r4 style compressor? I have bought all the AC components new and they are sitting in a pile because I cant for the life of me figure out how all these brackets go on  >:( I have found several pictures of trucks using the long compressors, but no luck with the pancake....  Thanks in advance!!!

The big bracket on the right goes on the exhaust manifold. Thyere are some long bolts that go through the compressor for the small brackets. The other bracket bolts to the front of the engine.

Thanks guys!!! Thats exactly what I needed. I think Im going to have to modify one of the brackets though. I have headers on my truck and the spacing isnt right without the factory manifold, not to mention my runners are bigger than the gap in the bracket.  >:( Atleast I know placement of everything now!

The typical modification for headers is to cut the large A-shaped bracket as shown in the following link and use a spacer under the front (only remaining) mounting bolt.

Thanks man! I figured I would cut the back off but was planning on cutting, fabbing, and welding a new mounting point to bolt to the headers..... Wow, was I over thinking things! Wait.....there must be a harder way!!!! LOL ;D
