I put hinge mirrors on my 31 Slant Window Cabriolet. Of course I needed longer hinge pins to accommodate the hinge plus the part of the mirror mount arm which spans the hinge. I also discovered that I needed a larger diameter hinge pin on my 68C. I found oversize hinge pins (B-46335-0SS) at Macs Auto Parts….and then I had to drill out the mirror mount arm to accommodate the larger diameter hinge pin.

Then I bought a convex mirror from an auto parts store for a few bucks and stuck it to the one on the passenger side.

They look good and are especially helpful when the top is up!
