Just curious to why you want a tilt body? I can see on a total glass truck like Dales that it makes sense because you need to make a subframe for it anyway and doesn't have to be heavy weight or all that strong but on a steel body, even when gutted as far as you can go...its still heavy and you need a major subframe to make it work and not flex when being tilted. Once you add the hydrolics to it, all the tubing for the sub frame and then aluminum floor pan if you want...you are back up over the weight of the original cab. I went thru all this 10 years ago with a Super Stock 4x4 I was building and almost broke both my arms when it came crashing down after a bracket broke do to some bounce from the cylinder.
On our new tube framed mod truck we are building (steel body) we have decieded to gut the cab as much as we can, we are running only fender skins and box skins, doors are gutted and a stock cowl hood and we are not going tilt body but just made a very very simple and very light subframe to hold the body in place. By going this route I estimate that we saved over 200lbs and is alot safer. We are running without a floor so its super easy to change gears in the drop box as access is super easy. We can also work under the hood very easily as we got rid of the rad support and could crawl in and have a nap in there if we wanted!
Just a thought...Tilt body is deffinatly cool, but not always the best solution.
