Aftermarket driveshaft u-joint. 83-85 5speed.
 

I have acquired a used aftermarket driveshaft with replaceable u-joints. It would be great to replace the u-joints as one of them has a broken grease fitting, and the rubber boot/seals are cracking. The driveshaft came from a 1983 model.

Does anyone have part numbers? Or better yet know of a vehicle that uses those u-joints?

Ebay 1983 RX-7 u-joint??

At the time of that post I thought I had an aftermarket shaft, and through research I think they use an old school mopar Spicer. After removing the joint and measured I found out I have a factory shaft that's had 430-10a joints replaced. I ordered some, problem solved.

Thanks for the help, but disregard the post anyway.
