help!!!!!what kind of CV join boots do I need!?!?

Since I am swapping my engine out, I have seen a few problems and 1 being that my CV join boots are gone. Now I have been calling around for them and they give me 2 kinds, SAGINAW, and a set with a bunch of numbers and letters. I have no idea which ones I need can anyone help me out?

how much do new boots cost? the only reason i ask is that rebuild axles are only 60 bucks at places like autozone, plus you get a warranty with them, might be a better option for future thinking, you will more then likely already have them pulled in order to do the boots, replace them now, go with the ones for the engine/tranny you are putting in. but if you want to just replace I think the dodgegarage has an axle id page on it
