Bench seat cover

[G-749]

Does anyone know who makes an " Indian saddle blanket" seat cover for a 68 -72 chevrolet bench seat, the kind that has the pockets on the lower part of the seat cushion ? The last 3 I have ordered f,rom Amazon, ebay are either to long on the lower cushion and hang in the floor , or are too long on the back cushion and the cutouts for the seat beltsare way too forward to allow the seat belts to cinch properly when you tighten them . Tired of sending them back .also tried the big box stores and they don't fit either. Only temporary to preserve factory seat foam till I can get $ to rebuild seats, my a$$ is tired of dragging over the foam/ springs getting in and out. TIA and good luck on all your projects.
