Mark Martin’s Partial Left Front Fender from the 1998 Save Mart/Kragen 350 @ Sonoma
Mark started deep in the pack in 26th, finishing in 6th place. Just a year prior he had won at Sears Point in dominating fashion.
This is the only race I can find images with the same contingency sponsor orientation and even the riveting from the now missing splitter brace aligns perfectly from race imagery.
