LMC Page The "right" or passenger side (#4) has a curved arm, and that seems to make sense. The "left" or passenger side (#3) has a fairly straight arm. However, when I try to mount it on the driver's side. the arm curves away from the driver. Is this correct? Also, do both mirrors mount on the front edge of the door - somewhat under the vent window? Confusing. Thanks! Dickson

There is a reinforcement piece with holes in it. Drill through those holes to the outside. | | | | | Joined: Jan 2010 Posts: 4,263 Shop Shark | | Shop Shark Joined: Jan 2010 Posts: 4,263 | Mounting location Drivers Passenger | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | LMC is incorrect in its listing of the same left-side mirror-arm for 47-55. There were two different arms, due to the addition of a driver's side (left side) vent window added in 1951. Here are photos of the different styles of miror arms (from Classic Parts). Originally, they were all painted lack - ignore the chromed finish - just look at the bolt/screw orientation to the arm. 47-55 right side mirror arm (passenger side) 47-50 left side mirror arm (driver side) 51-55 miror arm (driver side) | | | | | Joined: Mar 2002 Posts: 9,115 'Bolter | | 'Bolter Joined: Mar 2002 Posts: 9,115 | LMC also appears to show the larger rectangualr mirrors for 47 to 55, which is incorrect. I actually use them on my 51 but the passenger's side mirror didn't fit on the arm properly. I made an extension to the arm. | | | | | Joined: Oct 2012 Posts: 62 Wrench Fetcher | | Wrench Fetcher Joined: Oct 2012 Posts: 62 | Thanks guys. Very helpful! Dickson

Unfortunately, I couldn't find reinforcement plates under the cowl of my '50 3100. Is there a way to measure from the outside of the cowl? Keep looking. the holes might be plugged with bondo. They are there. You have to be a contortionist to see them. A good light helps. Carl
