Well you guys had told me either 3357 or 3457. I orderd them today and told them what kind of vehicle it was and they said P/N 3157 is anyone using that one
I checked the fittment guide on their page (that I found after I asked here) It lists the P/N 3157 for the 04s, the earlier trucks, it lists 3157 and 3457
I just picked up the blue/chrome silvanias from autozone this weekend to replace mine. Look soo much better now. Plus the amber coating was peeling off
