S13 diff in Q45 pumpkin?

[tristan89]

So I have a Q45 diff and axles on my s13, I hate the final drive ratio and the VLSD. I bought a welded diff, I want to put the s13 welded diff in the Q45 pumpkin, will it fit? Also do I need to change out the pinoins?

I want to make sure I have the Q45 diff, it has 5 bolt star pattern axles, it has the 4 stud back cover but it looks like they drilled 2 more holes for the diff that are wider than the stock holes. It also has a larger baffle on the bottom
