yeah im goin for mainly looks so im going to try and find a cage that bolts to the frame so i dont have to go through the entire body to get to the frame... would black look best for the cage color?
If you're mainly wanting it for the look then I would definately go with a cage that just mounts to the floorboards & be done with it. Add large backing plates to the underside and you'll increase the rigidity quite a bit. A cage will also have the added benefir of keeping the body tub much more rigid and you'll really decrease the chances of having the body cracks form right at the back of the rain-gutters on each side, this is a well-known Bronco problem and it's a bitch to fix.
If you DO go for the *much* stronger frame mounted cage I'd probably just cut the holes & run the tubes right down to the frame. I've done this and it wasn't all that bad. As JSM said you don't HAVE to cut the holes, you can run the tubes to backing plates on top of & under the floor but to be honest that just seems like a whole bunch of added work. I just cut the holes and then used some silicone & rubber trim to go around the edges. I put small driveshaft boots on the topside bars where they went thru just to make it look good and undercoated the bottom half.
Black is a good universal color but painting it to match either the body color or the trim/upholstry colors is also pretty sharp and has the added benefit of letting people see you went the extra mile.
