if u look at the 73 mustang boxes the front park lights go up and down, not like the 71 box go side to side, I love these mustangs, in 1983 I drove a yellow and black mach 1 to school everyday including winter, lol.
why couldn't you make the pull dozer stock using everything off a truck, I know the back cover is off but how many people used top drive these with the cover off, I had a 76 ramcharger that I always drove with the top off.
you would think how many caps/toppers are in the real world that a resin caster would make some different styles, model companies didn't make too many I don't think.
