Trader, keep asking your questions and we here will answer the best we can. Changing frames on your '58 truck is certainly do-able. As a matter of fact, I mounted a '57 GMC on a '77 dually one ton chassis and bed, using it for my "Home Depot" runs. I've also "clipped" a panel frame that was my daily driver for some 12 years. But as Deuce Roadster mentioned, there are guys out there that starts projects but never finished because lack of knowledge, tools, time, garage space and/or money. But that's what makes this hobby interesting...one could start from a "vision" or buy someone elses unfinished project. All comes out in the wash.
