1955-1970 Chevy Impala Bel Air Lower Seat Spring Repair Kit is a reproduction of the original GM part. This 3-piece set of 1955-1970 Chevy Impala Bel Air Lower Seat Spring Wire is a reproduction of the original. Whether you're replacing an entire string or simply need to patch up a few areas, the spring pattern fits wonderfully with the original wire. The wire gauge is thicker to accommodate the lower seat. We also sell the thinner wire for the upper portion of the seat. The kit includes 3 strands of the zigzag wire (50in length), 12 specialty upholstery clips, and installation instructions.
