whipplem,
How is the new lsd holding up?
Just a quick update on my part,i have finally removed my diff for inspection and all is as you guys have confirmed. L4 is ~38mm,L1 is ~125, 185mm ring gear. I havent measured but at a guess D2 is not the right size for any of quaifes either.
I will research the 210 case some more,im not keen on the 220 case,its massive and requires alot of extra work. i would look into a modified or custom lsd over this.
Yuk,whats all that black stuff in the bottom of my diff case? seems to be attracted to my magnet

i changed the oil with redline synthetic a few years back.
