hey all i am wondering if the seats from a 1976 98 regency would physically fit width wise in a 1978 delta royale. i can measure them but the cars are in seperate cities at the moment.. i have a gorgeous interior in my 76 that i would love to upgrade the delta's vinyl with. oh yeah, and im yanking the 350 for a 455 with a few mild upgrades while im at it.any input will be appreciated.. thanks, david in r.i.
