			[ QUOTE ] I have not seen any virgin hinges with the blue paint, was that a inspection mark from the hinge vendor or was it done on the line ?? cool picture [/ QUOTE ] Mike, If you recall the thread on the 1970 Harrell Camaro and this photo, you can faintly see they also had this large blue inspection mark. These were likely done by the hinge vendor. Somewhere I have a close up shot of the mark and it looks exactly like the hinges shown above. 70 DH Camaro Rick

			My bet is...the blue marks designated the sample piece and were marked after being pulled for quality control. Probably not found on every part...just some within the run. Typical in MFG...  Are right and left marked? It would not make sense to check every part made......  Steve  |
