I have strato buckets from a 66 Riviera. Are all the GM strato bucket seat frames from that era the same? I understand the sliders and brackets will be different. Are A body and E body seat frames a different size? Thanks.
At least foams are different from year to year and brand to brand. 72 tracks have wire connecting inside to outside. 72 also have electric connections for seat belt warning. Plastic backs and bottoms should all be the same 68-72. Less sure about springs
