These are reproductions of the original straight stainless side panel trim pieces for the early Impala models, the mid 60s to early 70s Chevelle, Camaro, and Nova models. This pair is 9 inches long. See other part numbers (#24153 through #24165) for additional lengths. The trim is polished stainless steel with factory type bend-out nails inserts and correctly finished, rounded ends, which replace the extruding aluminum pieces that are currently available from other manufacturers that have crimped, cut ends and sliding mounting tabs. These are sold in pairs only.
