Hi Brian, you lucky (hard working) dog riding around in a running RPU! Just a suggestion, take a look at the open car mirrors from Speedway, No. 751-AR17700P which are stainless and look to be light weight and based on a through-bolt stud. That type is available for '28-29, '30-31 and for '32. you might be able to machine a "cone" that would surround the shaft and give more support vertically or even a "Y-shaped" slab with a hole for the shaft through the bottom of the "Y" so as to provide a brace for the single bolt mount. Of course it might be tricky to put the nut on the inside of the windshield frame. If you get a chance can you tell me if you had trouble with your brake lines in terms of the check valves. I have already broken one aluminum fitting with a stainless steel male end so I am concerned to overtighten the stainless fittings into the aluminum checkvalves. Comments?
