4 Bolt rear end, is there realy a difference

[c711]

Between a 3 and a 4 Bolt rear end is there really a difference between the differntials? Or just the axles, hubs, etc are different?

Or let me say, if I have some 4 Bolt axels can I use my old 3 Bolt LSD with it?

Thanks

gear ratio I believe is different, plus I also believe the 3 bolt is a lot weaker of a rear end. If you do a search on rear diff you should be able to answer your own question.

Ratio is the same,there is only a diffrence between Manual and Auto Transmission.

But has ever anyone tryed to but some 4 Bolt axels in a 3 Bolt differential?
I guess the differentials are the some they only change the axels...

The size of splines going into the rear end is different (4 bolt splines are bigger). But all 5sp ratios for 90-96 cars is the same.
