As you know, almost anything is possible, however, the '60-'63 dash is not interchangeable with the 4-5-6 cab configuration. I have seen a thread on the modification, but I don't recall where. The wrap-around windshield & A pillar design of the '60-'63 trucks, makes the ends of the dash different than the dash opening of the 4-5-6 year trucks, but it can be done. This process is only limited by your skills, tools and dedication. Good luck and let us know what you decide to do.
