Hey guys, if any of you have your RX-7 LSD out of your car, i was wondering if you could measure something for me. I need the thickness of the outer part of the shell for the end that does not have the ring gear attached to it(the left side). In this picture:
I'm talking about the thickness of the left lip of the two halves. The reason I ask is because I bought 2 units (one from an automatic RX7, one from a manual) and the difference between them is visibly noticeable, measured around .060". I'm wondering if one of them had been machined down in substitution of shimming or perhaps it was just a casting difference (there are differences in the castings, probably from different years).
Another funny thing I noticed between the two, looking from the outside in one of the side openings where you can see the plates, what looks to be the friction plates (they have small grooves on one side of them), on one, the grooves of two visible plates are facing the same way, where as on the other one, 2 plates grooves are facing each other, as if someone may have opened the differential at one point (this is the one with the smaller lip).
I realize my questions could probably be answered by opening up the differentials themselves, but I was hoping someone could help me before I do that. Thanks!!
