Small update, installed the Robert Shaw High Flow 180 degree thermostat, ops and leak check good, may have to install a coolant overflow bottle. Jacked the rear end up, and sprayed the rear lower control arm hardware down with penetrating oil. I am going to see if the 91-95 GM B-body arms actually fit the 71-76 cars also. I have been told they do, and from what measurements I can get to without removing an original they look to be interchangeable. They will let me install the 7/8" rear bar I bought some time ago. I will post some pictures this weekend to see if they actually will work. The bar mounts on these later arms are very different than what I am used to on the stock GM arms of the 70's or 80's.

I have heard for years that this works yet I have never seen it actually done on a Pontiac, just a heavily modified custom LS Impala someone claims only needed it bolted in. Same with the guys who claim you can drop the '91-96 B-body rear ends in these cars with zero mods. If you can verify it after having actually done it, and with pictures, that would be most awesome.
