It'll be a lot easier if you just swap in the S13 diff. I have this exact setup in my S14 and it'll bolt right up with some modifications:

- Use your S14 rear diff cover on the S13 diff
- You need to shave down the front mounting bolts as the S14 ones are too long to use with the S13 diff (or you could get the S13 bolts if you have them already)
- You'll also need BOTH Infiniti J30 5 bolt axles, don't use the Z32 ones. The J30 axles are the perfect length but you need both sizes, one short and one longer. Best place to find these is at a junkyard, or post up a WTB ad on here.

Good luck, let me know if you have any questions.
