I understand the REV 2 and 3 are the best to use.


What is wrong with the REV 1 box and are the 2 and 3 the same?
What are the part numbers for the taller diff gears and what was the model and year of car they come from?

Thanks

We sell the final drive package- check our affiliates section.
Rev 1 boxes had single synchros and weak selector forks that were prone to bending.
Rev 2 onwards had dual synchros and uprated forks.Also, they were LSD as standard.

Best way to check is take a drivshaft out and look in the hole if it has a hex bar running through the hole then it has a LSD.
