Hello zilvia, after countless hours and visiting multiple forums my question still remains unanswered, I'm try to put. a q45 ring and pinion 3.5 final drive in a s13 open diff and then have it welded, I'm currently running a ls/t56 combo with a vlsd and it Doesn't feel as potent as it used to, and I've always wanted a welded diff but the stock final drive is cancer, so the most I have found about my question was, it's possible to swap a q45 R&P in a s13 with a LSD (tomei or kazz) , and I also found that you have to swap all the bearings and spacers from s13 pinion to q45 pinion, I have not found Any forums/ thread were someone swapped the q45 R&P in a s13 open diff, so please any help and info is mucho appreciated!
