OPG also has new plastic for the seat-bottom sides available in the same colors as the seatbacks. The material is a bit harder than stock, so be careful not to crack it by overtightening the screws. We were amazed by how well the plastic matches the color of the vinyl. Stock seats come with chromelike trim on the plastic (shown), and OPG offers it new. Ambrose doesn't recommend installing the chrome for use in hot SoCal climes because the glue inside it tends to melt and drip.
