That little bracket for 5.00 seems such a non-sturdy way to mount that mirror as its only shored up by 1 small bolt. Was looking at a jam nut behind the strip, atleast that strip uses 4 bolts instead of one. Mine mirror vibrates so bad right now. Was looking at that Y mount for a 1954 or the later one, that may be a possibility also, thanks much for the pics and links, I have a better understanding of what the assembly is suppose to look like, thanks HUGH
