I am looking to buy a good quality repro Sierra RS500 front bumper. All the ones I have seen have the black corner trim strips moulded into the bumper. I am looking for one that has been moulded without these so that original trims can be fitted as I think they look much closer to the original. Does anyone know if such copies are available and where one can be sourced. Also looking for a lower RS500 rear spoiler. Any help much appreciated.
