does anyone know where i could find u joints if possible (though i don't think it is) or a worthwhile aftermarket driveshaft?

 

I got a driveshaft for 250 bucks with replaceable u-joints, was modified at a local shop.

RX-7's come with non-replaceable u-joints so either you gotta get it modofied (like mine) or one from Mazdatrix.com.

Good luck.

 

Search for a thread buy audiofight about driveshafts and u joints. He posted links to a supplier to get the replaceable u joints and there were instructions on how to modify them to work.

 

rockforddriveline.com. (815) 962-1411 Talk to Stan. Buy part number 430-10A. you need two. Should cost you $50 with shipping. Big hammer, POS 9/16" socket a little cussing, you'll be amazed when your old ones come out. use a drimmel to completly smoothen the areas where the new cap is sliding in. It goes back together way easier than it comes apart.

Use 2 cans of spray paint to mark where the joints match up. IN other words if you take a can of primer and just shoot a straight line across the tow joints and the use a can of black or blue, turn the shaft 180 deg and shoot another straight line. when you go to put it toghether it will be easy to match up the paint.
