hey jorge i found some info you might want on that j30 diff you have.
J30 Diff
The Infinity J30 uses an ABS sensor that attaches to the input of the diff. If you have an ABS equipped 240, this will be the same sensor ring. This sensor ring requires that you have a drive shaft that is approximately .55" shorter than the non-ABS counterpart. If you do not have ABS, you will have two options. First, you can buy the ABS driveshaft. Second you can buy the non-abs diff input. Another important point to note, is that the J30's final drive ratio is taller than the 4.083 found in 240's and NA 300ZX's. The gear is approximately 3.9:1
didnt know if you knew this allready...
