The seat frames and springs are the same. The upholstery is completely different between 62 and 63 Olds. The upholstery is also different between Olds, Buick and Pontiac. I have not found anyone who offers the 62 Olds Cutlass/Jetfire seat covers “ready to buy/install”. Cutlass and Jetfire upholstery pattern, materials and colors are the same. SMS will make a custom set of seat covers on a “make to order” basis.
