66 dart seats
+1 For sebring seats. They have built in 3 point harnesses which works very well with old car that did not have an upper strap anchor. Try to find the later 04-06 era two tone leather/suede seats. They look good and have decent support, but might be tight on a larger framed driver. Generally they run $400 for both fronts on ebay.
The seats must be from a convertible. The 4dr seats do not have belts and do not fold.
