I hate the thought of buying a "new tub" IMO your losing all the originality. I feel if I were to buy a new tub I might as well by a new frame and start from scratch. Its kinda like buying an old cool house and tearing it down to the foundation and building something new on top...make sense? I understand if you don't have the time or money to fix something but it just doesn't feel right
LOL, felt fine for me, but I was never aiming at original, it was going to be resto mod the whole way. The tub that came with my bronco was replaced due to an accident. The frame is a '66 in great shape and the body was a '75 in horrible shape. The more sheet metal I pulled off, the more rust I found. I just couldn't justify all the work then have rust popping out through a seam in a few years.
It really depends on what works in your own mind. If you need all original it makes sense to start with something in good shape, unless you have lots of disposable cash or lots of time and experience replacing sheet metal. Then, at what point do you stop calling it original, after replacing 50% of the sheet metal? It's very easy to wind up in the situation where you just keep cutting, especially if you plan on keeping the truck.
There certainly are many really nice glass bodied Broncos out there. There will be really nice Broncos with steel replacement bodies out there in the next couple years. What would become of a good Bronco rolling chassis with the usual rotted out body that you find here in the North East without these options?
