Plain 'ol A36 is fine. You don't actually have a frame anyway, you'll be welding to sheet metal formed and spot welded in various thicknesses.

Yep. Its under 1/8" thick. I just did some colision repair on the front of my XJ.

People like to go heavy with steel, myself, I try to stick close to stock thickness. In an off road application, your frame (traditional or unibody) is going to flex. Making one section thicker than others can make one section that doesn't flex the same. Can lead to stress cracks at the transition points and frame sections nearby that now flex more.

cant find angle the right size in 1/8 or even 3/16 is it ok to use plate an all 3 sides and put in crush spacers every foot or two. i think i will also be adding my 4 link cross member now while the cargo area is being replaced how thick should that be

Plating is actually better than angle if you're trying to get it to fit up with an existing bent/formed area. Angle has a taper on the inside of the legs and a substantial radius in the inside corner making it fit not so tight.
