Haha i hope it works bedcause i already overnighted it XD. I'll compare it to the old one when i get it and let you guys know how it works

 

Wellp, got the piece in today and it looks NEARLY identical to the old piece. Same ID and same length but the metal lip on top is ever so slightly different (newer one is more pronouned/sqaure. And has a larger lip). It seems to fit well though...so i suppose i'll just slap it in and see how it works XD

 

Cool. I'll add the PN to my propshaft rebuild sticky.
