The part# 10174972 is the oldest and original part # listed in the GM SPO catalog and the number I posted is a replacement that fits all MY C4's and there's some fasteners that require changing. There are no structural differences. Either of these part #'s if located would do.

I realized your location when I responded and I mentioned Carlisle only because there will be many good eyes available to maybe "watch for you"!! An NOS C4 frame rail is pretty difficult "not to spot" when your doing the tour.

NOS is certainly the preferred by many but the used when cut and trimmed correctly will do as well, in many instances better!

I was going to try two days this year there but it looks like maybe only a Saturday and maybe not even Saturday.
