One of the stipulations when I was looking for my Regal project was it still had to have the AC in place and around here trying to find a unmolested Gbody that does't have a half *ss SBC install and all the AC stuff missing is no easy feat.120°F In the Shade here in Phoenix in the summer, AC is a must have. Mine is all there and working. I had to do some mods when I went to the Serpentine belt drive.
What I never understood is if you are removing a SBC 305 and installing a 350 SBC it bolts right back on.
