Racer57, considering that my "first time" (in a car, at least) was in the back of 1984 Plymouth Horizon, I don't know whether to laugh or cry at your observation. LOL!
But. . .getting back on topic: I've been doing research for a book I'm writing on the cargo volumes of various muscle & pony cars from the '60s & '70s. I've had great success getting both the manufacture's and SAE cu ft. cargo (trunk) volumes for Chevy, Ford, etc. But, for some reason, I'm having no luck with Plymouth. I keep finding "N/A" (as if the cars didn't possess a trunk!) Aside from the `69 Barracuda notchback, I'm also searching for the cargo volume for a `65 Barracuda and a`68 Road Runner.
I realize that my focus is on the 'opposite end' (i.e. not the engine) of the car that most folks on this discussion board are interested in, but does anyone have a suggestion (web site, book, etc.) for me?
