So the belts on my 86 Mj are dry-rotted, and I'm in need of some new ones. Problem is, I have too many options. Unfortunately I'm using my phone at the moment so I have no way to upload pictures, but I need the one that has the grooves in it, I belive it's called the v belt. I'm probably wrong on that though. I also need the smooth one. Rockauto has belts for my truck, but some day with ac, others say without and I don't know which ones I need. My truck does have factory ac, power steering, etc. Problem is, I don't know which belt is supposed to power what. Any help?
