rear cv ds pn rebuild q...

On to rear cvds rebuild, a Tom Woods unit when he was at SixStates, more than happy with his work, just my usual preventive maintenance.

Question is, I know 1310 uj's were used because of stock 8.25 yoke still in use, but... will the centering ball unit probably be the same as the front - Spicer C2-83 219 (stamped on old fds part, 211355X on Spicer Box)?

Thanks,

Eyeballed rdscv joint, totally different ball-centering assembly than front, took measurements, went to ds shop, 99.99% sure got correct Spicer part, useful info when confirmed for anyone w/242 to 231 tailshaft Currie-flange type sye...

Will post pix when confirmed...
