When doing the 5 speed conversion I decided to put a LSD - that’s Limited Slip Differential and not some psychedelic drug from the 60’s The easiest swap for this is a 40% lock-up 3.91 ratio out of a early 80’s BMW 320i. I with I could find a actual Alpina LSD but they’re worth more than I care to pay. This is a must have upgrade in my opinion. Currently the toot is a one-legged-dog. This will fix all those wheel spin issues I have going around corners... I just hope this used LSD I got from Double 02 Salvage works out.
