Trying to make a 1930's vintage truck a highway cruiser is going to be a very expensive lost cause. They were engineered to run maybe 40 MPH tops. If you install enough modern bits and pieces to make it run, stop, and handle safely at highway speeds, the frame and sheet metal will be about all that's left of the original truck.
There are so few Chevy trucks of that vintage left that it would be a shame to see one with the history yours has butchered up into a hotrod. It's your truck, and your money, but at least consider doing a real restoration, not another resto-mod that will destroy its collectiblity.
