ive searched everywhere and seen nothing, will a 87 mightymax bodylift kit work with some mods?

i guess im just asking for help to raise my truck a bit.

its a 86 ramd 50 4x4

i have 29'' tires and want to fit 31s thats why im looking for a small lift kit.

also looking for lsd diffs, rear mainly for now so if you have one ill buy it.

thanks
