I am thinking of mounting outside mirrors by drilling holes in the door "vent" windows.

I can do this with a diamond core drill if they are laminated safety glass.

I can't do this if they are tempered.

The windows should be marked as to being either AS1 or AS2.

AS2 would be tempered.

AS1 would be laminated safety glass.

My 2511 vent windows are 700 miles way.

Can someone please check their vent glass to find the AS1 or AS2 mark?

Thanks,

Larry

Larry,

Go to the 9 th page posting on my body repair thread and look at the second picture. You can see how a lip
Can slip under the window rubber will work. All you need to do is mount sheet metal maybe 3/8 larger in front and on the bottom so it will slip under the rubber. Call and I can explain the process if you like. Been doing it for years. Don Byers does the same thing. It works great and does not dammage the window.
Consensus is the glass is tempered so I cannot drill holes.

Yes Kirk, I know of the metal under the gasket trick. I am somewhat concerned of the weight of my Colt mirror and the fiberglass extension being a bit too heavy for glue or the metal under the gasket trick.

And again, 2511 is 700 miles away preventing any on the job discoveries or experimentation.

But knowing the drilling holes option is off the table at least narrows the solution selection process.

Larry,

You could hang 20 lbs. off that procedure---trust me on this. It is far better that any gluing process and I have tried them all. The only one that worked was when I blasted the window in 1981 and epoxied the mirror back on after it fall off and bounced on the road.

I have had good luck with windshield urethane holding to the glass but have not tried it on mirrors because this is the only way in install them now.

The plexiglass option sounds good but it scratches, becomes opaque, cracks, and is wobbly. It is probably more practical to glue a mirror to the stock glass using epoxy or silicon. I am in the process of replacing plexiglass with genuine glass on a new project because you cannot see through it to the mirrors. The plexiglass is cracked even though the car was stored inside. The mirrors on the car are Colt and I do not see an issue with gluing them to the glass. I had success for 10 years on a previous car with similar mirrors using epoxy. My friend has had similar success with silicon.

There are several types of plexiglas or Lucite. What we need for automotive use is UV-stabilized acrylic so the window does not 'sun-craze'. And tightening the mirror-screws too tight will stress-crack acrylics, too. The major gain is, the stuff is cheap: when I made my first set of front quarter windows some 18 yrs ago, I made five of each side. I just installed the last of that 1st batch, each of which cost me $3.
