On my first EB, the PO put a 289 into it that should have gone into a race car. The guy that bought that EB from me found out that his 19 year old PO grenaded the front end & transmission due to a very heavy skinny pedal.
.....Wish I still had that engine, I'd be putting it into a Mustang for my dad right about now. My current one the PO used sheet metal strap to hold the floor board under the dimmer switch up & used a BFH to fit & then weld some "C" channel for both bumpers onto the frame.
Not on the Bronco, but dad's Mustang, the PO used aluminum, covered by an inch of bondo, covered by a stop sign to fix the rust problem in the passenger side floor pan. Real fun cutting that crap out.
