Don,
I bought some items from a local gentleman who had 6 41-46 trucks torn apart and had all intentions of building a good one. He was in a bad wreck and fell upon some bad medical times. I bought this mirror from him. It has a single bolt mounting that I plan to install in between the wiper panels like so once I get my seats in for placement. Glad to hear dislikes with peep mirrors as it was my plan to install those also. I think this mirror will look period correct.
