Okay. Ive been looking around, researching, the mk1.5. I heard the st165 axles should pretty much bolt on to the rev2 3sgte, right? This is what confuses me. Some people say they are a no modification needed thing, while others say their too long. All this cv joint swapping with this axle and this other thing is really confusing me

. Can anyone dumb it down for me. Oh, im new to this engine stuff so.... Whats a cv joint, whats an outter axles and an output shaft

. What do they look like. I have the celica st165 axles with me.
