Correct lift kit?

[B40003]

I have a stock 1994 Mazda B4000 SE 5 speed. Went on my first offroad run with a local club and had a blast. It did pretty good stock, nothing insane but I'm looking to make it better. I'm looking at Yukon Grizzly Locker for the rear but I dont know or where to find if my truck is 28 or 31 spline. Also I'd like to get 33s, would a 2 inch lift work?
Any advice is appreciated,
Thank you for reading.

You should have a 28-spline 8.8. You'd have to have a 6-inch lift for 33's. For a 2-inch lift you'd need to add a 3-inch body lift.
