What kind of car do you want to put the seats in? Reading between the lines, not another R129! In which case, my instinct says No.

The seats in the R129 are quite unusual. They form part of the roll over protection for the occupants of the car. They have a substantial and bulky magnesium frame. It would surprise me if the seats fit into the car in a standard manner.

The seatbelt is part of the seat frame. All of the cars have a very complex electric seat adjustment system which automatically adjusts the angle of the backrest and the height of the seatbelt depending upon the position of the squab.
