Before undertaking the rear suspension rebuild and assembly, we wanted to get the differential rebuilt and in place. This is critical because the suspension’s Roto-flex couplings and half shafts mount to this differential.
Based on a common English Ford unit, the front half of the differential is nothing fancy. What makes this differential special is not the ring and pinion …
Did you install the stiffening bracket that spans the upper mounting ears on the aluminum casting? Lotus added these to later Elans. If not, it may be worth considering. I'm following this restoration with great interest as I am restoring a 1972 Elan that has been sitting since 1987.

I did not add those stiffening bracket. We are trying to restore this as close to original as possible. I did stiffen the engine mounts, as they were torn.
You may want to talk to Ray @ R.D. That differential bracket was a running change Lotus made, I think with the Sprint. It is a pain, even with the body off.

I have been talking to Ray at least once a week, about every step in the restoration. He has been a great resource and a great guy.
