WTB/WTT 4.10LSD for 3.73LSD

[gearheadE30]

I have a 4.10 small case LSD in my 318is that I need to replace with a 3.73 LSD. My diff is pretty quiet; has a slight hum from 60-70 mph but it has an AKG poly bushing in it, so that is probably why. Clutch plates are good; has new output flange seals and fluid as of 3k miles ago. Looking for a trade + cash for a 3.73 LSD, or looking to buy a 3.73 LSD for $200-$250ish shipped. Let me know what you've got.

Thanks,
Jordan

bump. a 3.91 or a 4.10 would also be fine. Just has to be medium case and LSD....

did we talk about the 3.91 viscous lsd I have? I have plugged this diff too, I have lost track.

No, I don't think we have, but the car sees enough autocrosses and track days that I'm really leaning more towards a clutch-plate LSD for the predictability and consistency.
