Okay, I've searched through this forum and have read the page on body panel date codes. This is the rear floor support on my '67 convertible. The car was built 11D. From reading the CRG page on body codes it appears that K stands for the manufacturer of this piece and the 41 is the week of the year. In this case like the second week of October 66. What does the 7403 mean?
Always looking to learn something new!
Thanks everyone!
