There are two styles of oval seats. If you have the early type without adjusters on the front seats then they will probably feel like the backs are in a slightly reclined position. This is due to base having a different gradient for the runners as the early ovals have a different floorpan pressing to later cars. There are also different fixing mechanisms for keeping the back top half of the armrest locked in position. If you have a set of good condition oval seats then they should sell easily on this site and a set of 63 seats should be relatively easy to find.
