I own a 62 ford galaxie xl boxtop that is in excellent condition.I stripped the car to bare metal and found no bondo and only a little rust.I want to customize this car by swapping the boxtop roof(I hate it) with a 61 starliner bubbletop roof or any of the 61 bubbletops (buick,pontiac olds 0 all had bubbletops.How do i find out the dimensions on the other cars without actually seeing the car?Is there a m,anual that would give me this info? mike
