Any 1942 - 48 GM 'A' body 2-door front seat should bolt right in; Chevrolet (Stylemaster or Fleetmaster), Pontiac (25 or 27) or Oldsmobile (66). Measure the bolt spacings in the floor pan for each track (L&R) and width; You may find 'B' body seats could fit with minor modification; Pontiac (26 or 28), Oldsmobile (76 or 78), Buick (40) or Cadillac (61); or The larger 'C' body seat may be too wide, however measure and you might be surprised; Oldsmobile (98), Buick (50 or 70) or Cadillac ( 60 or 62)
Am in Colorado I have the original seals but they need to be replaced or redone. I think the back seat is going to be the hardest to find one that fits. would like to just put new after market seats in
