Long hood mirror adjustment

[RD911T]

I have a rectangular mirror I bought for my 71. I know it's not correct, but I like the chrome or stainless look and I bought it before I realized my car should have a round mirror. It's in pretty good shape except for the corrosion in the adjustment nut.

The mirror is too loose when installed as in, once adjusted so I can see out of it, it is obviously going to move as the car hits bumps, etc. Inside of the bottom is a nut that compresses a spring. Problem is that mine is very corroded, as mentioned above. I'm soaking it in Kroil now, but I'm wondering is the stud that the nut and spring are on an integral part of the mirror or if I force it and the stud breaks, can I replace it? Or can I cut the nut off and then replace the stud if necessary?

Kroil should do the job and allow you to remove the nut. Unless you are saying the whole mess is badly rusted. Still, there isn't all that much torque on the nut. Once you get it apart, you will see the nut, small washer, spring and large washer. Remove all that then there is the base with a conical washer (hex hole) that fits over the stud which has a hex shaft.

Can you replace the stud? I'm not sure if just unscrewing it from the mirror will work or if there is a nut/washer on the inside of the mirror of which you can't get to unless you remove the glass. That could be a PIA without damaging the glass and rubber gasket.

Thanks, that helps. I already replaced the glass, so don't want to go there. I'll keep the kroil on it and after a while try hitting it with my 3/8 electric impact.
