Grandpa Posted May 29, 2009 Share Posted May 29, 2009 The optional right side outside rear view mirror on my 1941 Buick convertible in next to useless because it has a flat mirror. I would like to replace the flat mirror (in the original circular shell) with a convex mirror with the same radius of curvature as that used on modern passenger cars. The federal requirement (Vehicle Safety Standard, Part 571, Subpart for right side outside mirrors for passenger cars is a radius of curvature not less than 889 mm (35 inches) or more than 1651 mm (65 inches). A mid-range radius of 1270 mm (50 inches) would be preferred. I don't want the warning text (which wouldn't fit anyway) or an after market paste-on mirror. I would like the installed convex mirror to look as close to stock in the original shell as is possible.Do any forum members have suggestions as to an individual or business that can cut a passenger car convex mirror to a specified diameter?Thank You,Grandpa Link to comment Share on other sites More sharing options...
keiser31 Posted May 29, 2009 Share Posted May 29, 2009 Moss Motors in Goleta, California sells convex mirrors for MGs. They should have one to fit. Link to comment Share on other sites More sharing options...
Grandpa Posted May 30, 2009 Author Share Posted May 30, 2009 keiser31,I need a mirror of 4-7/16 to 4-1/2 inches in diameter. I contacted Moss, as you suggested, and they do not offer a mirror that large and they do not custom cut mirrors to a specific diameter. Thanks for the tip anyway.Grandpa Link to comment Share on other sites More sharing options...
Larry Schramm Posted May 30, 2009 Share Posted May 30, 2009 Just a thought, Did you try a truck supplier/ truck stop. Some of the add on mirrors might be about that size. Link to comment Share on other sites More sharing options...
Grandpa Posted May 30, 2009 Author Share Posted May 30, 2009 Hi Larry,Convex truck mirrors (and motorcycle mirrors) are made to a different radius of curvature than passenger car convex mirrors, per the federal standard. Your suggest will be my Plan B.Cutting down a large passenger car convex mirror isn't a good option, as some of the warning text would likely end up on the cut down circular mirror.Thanks,Grandpa Link to comment Share on other sites More sharing options...
Dave_B Posted May 30, 2009 Share Posted May 30, 2009 Grandpa, I think a good glass shop should be able to handle that job. I have had the right side mirror replaced in late model vehicles and they told me they are required to use the curved glass on that side.(Is the new software gonna have spell check?)Dave Link to comment Share on other sites More sharing options...
Barney Eaton Posted May 31, 2009 Share Posted May 31, 2009 I use a mirror from WalMart about 3" in diameter...then go to the craft department and get a big suction thing.Bond the suction cup to the back of the mirror. When I get to a show, I remove the convex mirror until I am ready to go home. Jay Leno uses something similar on his cars but I could not find the one he has. It is rectangular and he sticks it on the inside of the vent window....then cranks out the vent window to give him the view he needs. Link to comment Share on other sites More sharing options...
Mark Shaw Posted June 1, 2009 Share Posted June 1, 2009 I saw the same episode of Lenno's garage. He uses a shower mirror made with a suction cup to attache to the shower wall. You should be able to find them in the bath acessories section at a drug store. Link to comment Share on other sites More sharing options...
Barney Eaton Posted June 2, 2009 Share Posted June 2, 2009 I did more searching today and could not find a ready to go convex mirror with a suction cup. The one that Leno suggested might be like a boat mirror but I have never seen one with a suction cup. Here is a photo of the one I made, attached to the existing mirror.
