the Diff was a BMW unit from ebay. $120 to my door. I got a second one for half that. Everyone wants the 4.10 ratios and the 2.93 is give away pricing there. Believe me,the engine has LOTS of power to make a 2.93 move. The drivehshaft is 23 inches x 2 1/2 diameter.
I wanted the LSD to limit the nasty torque steer I was likely to experience with an open diff during shifts. It was a challenge to setup and install. I would suggest to setup some very good measuring points under the car and with the diff. You should be good to go as long as you stay true to equal measurements. I have to admit I had my fingers crossed things would work out. It turned out to be setup just right. NO vibration from 5-120 mph.
I've posted pics of the engine install, diff and rear end before. I had recently picked up a 4.10 BMW diff with the hopes of swapping it out to see what kind of damage I could do to my tires. I have yet to take it to the 1/4 strip - it's still rainly/cold in Alb.
Next step is to finsh up the body work and put a paint job on it. Still looking for a home for the old engine, diff, radiator, seats, tranny, hardtop, air conditioner, ....
Oh, btw, SBC, 600 cfm holley, 58 cc aluminum heads/header, roller rockers, 700r4 tranny w/od, foam sound/temp insulated under carpet all interior (very quiet). I even replaced the cardboard gas tank cover with a steel one. I rejetted the carbs for the high elevation here(much nicer to ride without smelling un burned fuel....)
details, details...
