Would like to install the wheel pants that came with my C150. Problem is, it appears that the cover plate is missing from the wheel pants. If I'm understanding the parts manual correctly, for my a/c (s/n 15072865) it appears I should have p/n 0743625-15. This should be for a 1971 - 1973 C150L. Any one have one they might part with?
