Is there any specific type of freelander diff that is commonely used in BEC installations?

Hiw do i identify the right one

Also whats the going rate for the right one.

Cheers

I have an earlier one (2001), they're supposed to have bearing problems, but I haven't had any. Basically any Freeloader diff. will be superb, they're 3.2:1, perfect for hairdrier applications.
You need the Quaife ATB version, so new, not locost (£1000+). 2nd hand, dunno.
