I have a 91 miata with the B6ZE(RS) aka 1.6l I'm having this poping sound near my drive shaft and I'm sure I located the problem. My u-joint in the drive shaft has gone out, I've been deciding on either buying a whole new aluminum drive shaft with a new u-joint or finding a used one. What do you guys think I should do also I have a vator bodykit on it, should I get rid of it and take it back to stock?
