That gearbox looks like you wasn't even there doing any conversion mods, well done.
Diff gears are pretty stout, it's the UK after market ones that are soft, designed to wear and sell more.
Ok which LSD unit are you getting?
Seems everyone wants the 3j , it's fine for fast road, track as is all of them..
I'm going to hopefully get a Blackline LSD for my project, it works like a quaife but also cheaper , just my 9c worth.
Small history lesson is 3j used to fail when they was new on the scene 25-30yrs ago, they'd small the bearing carrier off the centre , they are totally fine now, just a company learning curve at the start, we had 4x failures with mild Pinto and 1 with Nos.
Please say you got tramp bars/brackets installed on the body , I forgot to look at pics before
