Hello i do not have much do to with sierra's but I thought I would try on here for a little bit of advice/help. I have a unpainted and undrilled rear bumper which is a zender rs conversion bumper and I believe it to be from the 87-onwards rs catalogue.
I was wandering if anyone would be able to give me a bit of advice? Im not sure how rare it is and things as I can not find out much about it.
I look forwards to your replys
Many regards Tim
