Re: Diff ratios for E28

[Jerry Brown <jerbrown@xxxxxxxxxxx>]

Ken,

If I'm mistaken, my E24 ('88 635 CSi) has the 3.64 LSD. While these cars
are certainly not as plentiful as the E28s, it gives some more
possiblities. Since the E24 is based on the E28 chassis, my
understanding is that most stuff just bolts right up.

Now, if someone was to offer to swap a 3.73 LSD for my 3.64 LSD, I'd
probably give it some serious thought. 

Good luck,
