unibody question..

I realize a stock truck frame flexes and the bed has to be it's own piece to allow for that flex, but when building these frames that you guys build, is this flex room necessary? all seem "overbuilt" and flex always seems to be a topic at hand.

Where is the difference in a car frame and full custom truck frame? Are car frames really that much more sound, and I don't mean sub frames, I mean like crown vics with full frames and all. Wheres the huge difference between a full frame out of a vic, and one under an s10?

on cars, its more of how the car is built rather then the frame.trucks dont have the inner structure that cars do.

feel free to correct me, but one main reason i've learned is load. trucks weren't built to be lowered and carry people everywhere, they were built to carry load in the bed, so the bed needed most of the room to flex. that load adds extra stress to the chassis too in that specific area. most trucks that are getting stock floored and what not, aren't going to carry a lot of load or any extra twisting motions. cars, also, have structural support through out the body, unlike trucks having the structural support through the cab. and i've noticed most cars used a more boxed frame, where as trucks are normally channeled

ive just seen trucks put on cars frames and unibodies with no problems and no "extra" bracing.

is it safe to do so a full frame built with some extra support like the usual custom mini frame?

anyone else? im think about (way later) cuttin the roof off and going unibody with my 72.possibly making it a long bed and throwin seats all the way back, but under the bed rail so i can somewhat seal it up when i need to.
