Used LSD from 928intl costs under $1000 if they have them on hand. Other than that gearbox needs to come down and will require adjustment of shims. It would be stupid not to change bearings and seals at same time. Cost of installation depends totally on who does it. Between DIY and most expensive shop in town, difference is probably $1000.

I don't think the gearbox needs to come out. Measure backlash before removing the open diff, transfer ring gear to LSD unit and replace restoring the same backlash.

It doesn't have to come down totally but I think its impossible to change diff without lowering it some. '78 My might be expection as battery box can be taken aout of the way on those.

Hi Samantha,
Which gearbox do you have G28/?? I have an LSD w/ 2.75 in a complete gearbox, which I would consider parting with the rear-end section. The LSD is really tight, and feels more than 40% but who knows. Also I have new dual cap distributor for the 84/85 euro's that needs a new home (box is collecting dust).
If anyone can help determine if a G28/05/08 rear end will mate clean, it would be helpful.

if all else fails (and i know this procedure sucks), but you can always count the ratio of turns between the ring gear and the pinion gear to get the gear ratio.
