Let's back up here. Do you have a 59 truck? If so, what is wrong with the frame.
Secondly, I've owned lots of TF trucks (55-59). The advice is right on, keep the frame and "restore" it and update it. All is available and has been done by many, many members. One thing that has not been mentioned is that there is a large list of headache issues regarding mating a S10 or other frame to the existing body. I.E. body mounts, brake/ebrake and gas pedal linkage/system, donor frame shape, wheel base and width, stance, shift linkage. Fender, radiator, bumper and bed mounting. Steering box/shaft/column fit. Motor and trans mounts and location to fit body. Frame width vs body width. Tire rub..........destroying value of the 59, more costly to complete, as so on.......
