I've got 2 cruisers. A 77 that's all stock, uncut, with the 4 spd tranny. And my 72 that someone has already opened the rear fenders up on and cut the front fenders. The 72's in too nice of shape to beat it on the trails hard but not so nice that I would'nt want to take it out for some mild wheeling. I'm really wanting to build a trick rear bumper as well as a front bumper for it and maybe some extended tube shock hoops for the front. The bumpers I'm wanting to build would require me to torch out the rivits on the rear and remove the stock frame cap. Think I'd be fawking up by cutting this much into it?
