Bracket for rear view mirror

I think that you will have to fabricate one yourself ,as the original clocks had the bracket which cosisted of two pieces installed on the body of the clock and held on with small screws and the two brackets had small slots which allowed adjustment to hold the cloc in place . If you get a copy of the Auburn Cord accessory book from the ACD museum , you will see a great illustration of the mirror and the Phinney - Walker clock that they used on the 8-98 models , Hank Reus

I own a 1931 Auburn 898-A. The rear view mirror has a non reflective area on the right side of the mirror. This was done to allow attachment of a clock on the back side. I bought a windup grandfather type watch that fits the space intended for the clock but am having trouble improvising getting a bracket to hold the watch in place. Does anyone have any suggestions where I might obtain a suitable bracket for the watch to be affixed to the back of the mirror ? Much thanks. MA
