When we had our 49 it didn’t have a right side visor didn’t have any problems, that was about 13 years ago. The 51 we bought last May did not have a left one, got the parts from the filling station got it on but not easy. I repainted the interior and needed just the visor for the right side, got one from Classic Parts ruined it trying to get it on the original bracket. Decided to order another one and a new bracket no luck with that. Called and sent pictures, we decided they would install a visor on a new bracket and I would just pay for the visor, and no shipping charges. Few hours later they called he had ruined 3 and gave up. Going to try getting the bracket from a different suppler, waiting on that now. She also told me others have had problems also.
I wasn’t sure what to try for a lube that would not stain the cardboard visor.
