I don't know if the parts are inter changeable but if they are I will trade you a trunk package for the rumble seat package, even up ! Wayne
If my wife would have caught me in the rumble seat with her sister I would think it would have resulted in a fatality. .........or two.
Come to think of it,I've never ridden in a rumble seat.I've owned 3 or 4,but I can't remember riding in one.I have two dogs that ride in it,but only one can fit in it at a time.I can remember when I was little having to do a chin-up to see over the dash rail.I usually rode standing up,looking through a windshield that one of my uncles made out of a peice of glass they brought home from the dump.

Kevin in NJ (and others): It's not much but I use a piece of round split foam that's made to insulate pipes on my rumble seat rails. Like I said, it's not much, but it could save some facial surgery on the grand kids. Oh, and I pray a lot when they're back there too (but they love it!).
