At the bottom of the Diff in this picture, the ID of the bolt holes is much wider than an S13 diff.
however, there are bushings that go in there… i need those bushings or at least the part number for those bushings so that i can order them from nissan.
55424-33P00 are the bolts that hold the differential in place. I was just talking about the nismo bushings for the subframe and the diff.
btw, you could try Courtesy Parts
Those bolts are cheap, but they are out of stock. When I got my rear LCA’s from them, they were also out of stock, but I got the guy to check if they can get them from anywhere in the US. It took him 10seconds to find a set somewhere in LA. You could do the same, just give them a call and let them check for you.
