Firstly, let me extend a hearty welcome to the Jeepz family
I think your 86 Jeep could either have the 2.5 or the 4.0 inline 6, do you know which one yours has?
An excellent source for Jeep parts is
Quadratec
If you call them they will begin sending your free catalogs just for your model.
What parts are you looking for in particular?
