I am restoring a 70 Boss 302, build date 6/29/1970 at the Dearborn assembly plant. In cleaning up the transmission mount I have found what looks like Ford Corporate blue engine paint on the mount (See Pictures Attached). The paint is on the rubber and bare metal portions of the mount and is on the portion of the mount that would have been mated up to the transmission when installed indicating that it was likely put on before the mount was installed. All research that I have seen indicate that the non-rubberized portions of the mount are not painted. In addition I am essentially the second owner of the car and the original owner said that the car had not been apart before. Has anyone seen this before? Did some mounts get painted? Is this possibly an assembly line color marking to assist the assembly process? Is it something I should try to reproduce while restoring? Any thoughts or opinions would be greatly appreciated.
Thanks
