Hey everyone!
Toying an idea of installing a locker (not an Limit Slip Differential) into my E34 535 5 speed.
I have about 8-9 years experience with such devices running them in my Jeep Cherokee (both axles) so please no education on the matter :-)
Why I'm asking fine people like you is to locate a source of such devices online. Please if anyone knows the source, I'd appreciate your help!
Full locker would be better choice($$), however, a spool will do just fine...

Thanks in advance for your help!
