This custom quality kit is made with better-than-original materials to replace, not cover, your old outer seat material. It isn't a universal kit, but a professionally designed re-upholstery kit that was constructed to properly fit the rear seats of your 74-78 2+2. The original-design foamed pleats are sewn into the seat bottom and back rests. This kit includes step-by-step instructions and all of the necessary hardware.
This is a SPECIAL ORDER item and may take about 2-4 weeks to make.
The image above shows the 77-78 style kit with "basket weave" insert. 74-76 kits will not have the basket weave center.
Black and off white kits will have the "basket weave" material in the center of the seating surface. Unfortunately, dark brown is not available in this style.
