Thanks guys. My Jeep did not have its tub off in its lifetime before I got it, but the grille was off probably for it's several engine changes, so it was a mixed bag of broken and missing fasteners and no insulators. I think I will put some sort of rubber insulator between the grille and frame.
I did notice rubber welting between the rear part of the fenders and tub though.
I like the leather washer idea too.
I might buy a chunk of conveyor belt rubber for the tub insulators. Amazon sells it (sheesh).
Whew. I thought I was making progress, but man, putting this back together is going to be a BIG job.
