This is to let everyone know that the correct replacement u-joint for the 2nd gen NA RX7 is the Rockford 430-10A. Other posts have incorrectly listed the 430-10 not the 430-10A. The 430-10 is about .002 thinner which results in a loose fit, which is "bad news". The Rockford application info lists the 430-10A and this is the part I used on my driveshaft. Perfect fit---no shimming! Hope this info helps! You can check local driveshaft shops for the part or order direct from Rockford (www.rockforddriveline.com). About $20 per u-joint

 

These are for the NA driveshaft right? You cant use it on the TII driveshaft.

 

Yes, this is the NA.
