You'll find a lot of discussions about old plymouths here http://www430.pair.com/p15d24/mopar_forum/forumdisplay.php?f=2
Here's a '54 Plymouth coupe. New at posting this so bear with me. It's on a '82 (?) El Camino chassis, channeled 4" as I hope one photo will show. $250 front and rear ends with proportioned brakes, power brakes, power steering. Eibach road racing rear springs, one-coil-removed heavy duty front springs, 354" Chrysler with 350 Turbo. No-body-work frenched front lights with International Travelall aluminum accents ($1 ea.). Louvered front fenders, "basket mags" with adapted stock hubcaps. Gas filler in trunk. Extended back panel, chromed window revels, flipped front bumper, partially nosed, partially decked and some more. Hope I can post some pictures.
