After a lot of chasing around and bidding for 'burb seats, only to be beat by someone willing to pay more, I have found stock appearing seats from a '58 International Travelall. The center seat is 39" overal length including the armrests and the back seat is 48" wide-a little narrower than the gm seat. But the schoolbus type frames with metal backs resemble the gm seats and most important, the price was right! There will need to be some mounting modifications, but nothing serious or difficult.
Email me for the photos if you want to see them or if you can post them here.
