Attached is a copy of a Template for the companion RH, 1967 Mirror, that I modified and added dimensions to several years ago. Measurements were taken from the original Ford template that came with my NOS C7AZ-17696-C, RH Mirror. The original template is 21-1/2? long, which exceeds the limit of my 11 x 17 Printer/ Scanner, which is why I made measurements and shortened the template.
That all being said, one would think (?) that the template for the RH mirror would have been designed to position it at the same relative place as the Factory LH Remote Mirror. If that is truly the case, then the LH template should just be a mirror image (pun intended). Unfortunately, as my 67 is at our Colorado p[ace, so I cannot confirm this at the moment. I did, however, bring back both my LH Remote and my old RH mirrors to Omaha in order to ?work on them? over the Winter. Interestingly, the RH Mirror came with the identical plastic gasket (with a hole in it for the remote cables), as the LH Mirror. This gives a center to center location of the hole for the cables, but not necessarily its size. The large hole in the gasket is 13/16? ID. I have shown its location on the mirror image that I generated from the RH template.
Hopefully, Richard can verify both the dimensions that I have added, as well as the size of the hole in the door for the cables, on the shell he has.
Once verified, I?ll make a readable mirror image for future use.
Hopefully this will help.
