I have a 1954 panel with no rear suspension installed. I have a Mustang II front K member kit. I also have a 1980 Chevy 1/2 ton with a good 350 and auto trans. Should I mount the panel onto the Chevy chassis or, stick with the 1954 chassis and put the Mustang II front suspension in and use the rear end from the 1/2 ton 1980 Chevy truck? Thanks ahead of time....Bill
