As a follow-up, here is a link to an eBay ad (Not Mine) offering a full set of both left and right cab "outer and inner rocker panel" patches for a very inexpensive price.

Full Rocker Panels w/ Inner Patch Panels For 67-72 Chevy C10 Truck LH & RH Side

Since the C50 cab is the same as a C10 cab, these should work based on the info you provided so far.

Hope this is of some help! wave
