You are absolutely correct. In my quest for used parts over several months I found several J trucks, wagons. and even a 70's cj all with the same set up of brackets, pulleys and ps pumps. The biggest problem was finding these parts in a usable condition. Most were either accident damaged or too rusty to repair. I did notice the J-20 donor had ac with a single belt ac. It still used the same water pump pulley and alternator pulley set up just a longer belt to accommodate the ac. I never encountered one with a dual ac belt set up. Probably because I only searched out earlier model vehicles. I also noticed the 360 engines were the most common. Even an old AMC Manatodor car had the same PS set up.
