WTB: 4.10 Differential in SoCal for pickup

[PDRbmw]

I am told I need to replace the 4.10 rear diff in my '91 318i 4-door, manual transmission.

If you have one that is/was working well when removed, and it is available for pick-up in So Cal on short order, please contact me.

Thanks.

Do you need it to be a limited slip?

MR 325...

Yes, I'm told it is 4.10 LSD...and my mechanic threw out 4 other numbers "9931" which I couldn't understand through his accent if that was an important component of the LSD part or a part number itself?

Experienced e30 mechanics/enthusiasts can likely teach me what that is...but for now, this is all the info I have to go on.

If you've got something that may work, I'm in SoPas and could zip over to LC this afternoon or tomorrow.

Thanks.

One more part I also need is the driver's door lock actuator. Any chance you may have one of those, too? I'll send you a PM with my phone #.
