i am going to strip a crx for all for the mpfi stuff. i might also want to get the cv's as part of the deal. how do you check them to see if they are good without driving them? mine clack like crazy my 7 year old nephew calls my car the popcorn car. autozone rebuilt units are only 60 bucks a pop. is it worth messing around with them or should i just go new? is there a step by step guide to changing out the cv's? i have only done saab cv's in the past. they were a real bitch. thanks.
