I am looking for information on door mirror replacement. I just finished the body on my 78 3/4t and want to install the mirrors. The mirrors I have are the Dumbo style and the glass is broke. Can you replace the glass? if so how do you get the old out?. My other option is to go to aftermarket but all the heads I find do not have the mount like mine. I have a tube coming off the bracket that goes into the mirror head and there are 4 small bolts that must clamp it inside the mirror head. These are original to the truck.

Mirror mounting dimensions are available in the thread Optional Mirrors (http://forum.73-87chevytrucks.com/smforum/index.php?topic=18539.0) located in the Technical Pages. Generally the glass is replaceable if you can source it. IIRC the glass is retained by double sided tape, but what you've described sounds like more trouble than it's worth. Why not replace them with stainless steel mirrors?
High quality stainless steel mirror kits are available through the 73-87ChevyTrucks.com (http://store.73-87chevytrucks.com/merchant2/) site store. Click on "Doors" and scroll through the subsequent pages. If you have any questions about the mirror kits, email Captkaos at webmaster@73-87chevytrucks.com.

Right, but I do not want to go to a different mirror, the style shown on that site is a newer version than what I have and I would need to weld holes shut and repaint the door again. I really want to stay with the original style mirror and just want to replace the heads. I understand the difficulty with replacing glass, just wondered if anyone knew of an easy way to do it. I think I will try to find used ones or replace just the heads. Thanks.

Got it. Here is another thread showing "Dumbo" mounting dimensions, 73-87 Mirror mounting location (sport and "dumbo") (http://forum.73-87chevytrucks.com/smforum/index.php?topic=15584.0). Good luck with your project.

Which mirror do you have?
-
White Dumbo, rod from mount actually slips into head and bolts clamp it down
-
Does your mirror look like the one in the attached photo, except white painted?

If it's a mirror like in the photo, there is a rubber gasket that can be carefully pried out and replacement glass installed.
-
That is it, when I tried to get it out the mirror cracked. Is the mirror glued into the head?
-
I don't recall there being any glue between the rubber gasket and mirror body. Just a really tight fit between the gasket and the metal mirror body.

Jason is correct. Usually just a tight fit. Very difficult to remove without breaking. Putting new one in requires lots of lubricant (we just use foaming glass cleaner and maybe a little Vaseline). You stretch the rubber gasket over the new glass, then press the glass and gasket into frame. However, I have seen some people use a little urethane or silicone on the install.

Both of these are correct. I've done it numerous times. I've never used a lube tho, I've just always been careful.

Thanks a lot, I was told that the glass was glued to the mounting block in the back. We have a good glass place in town. I will try to see if they can cut it the same. or is there a place to get replacement glass?
