More noob questions about rearends
 

I was looking to buy an LSD for my 88 vert. My question is if I should go with a TII rearend or a GTU rearend. Btw, I appreciate all feedback :)

A TII rear end will require upgrading to the entire TII drivetrain. Or making a custom driveshaft and custom half-shafts to make it fit the NA stuff.

I dont mind doing the custom stuff just wondering if its better to get a TII rearend or stick with a GTU rearend. Im trying to set up the car for drifting so I know Im going to have to upgrade a few stuff. I know that the GTU gear ratio is 4.30 and the TII is 4.10 so I'm just wondering what would be a better diff to go with.
