Tripod Mirror Mounting - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Your41Plague12 · 09-04-2012, 10:05 PM

I just got a pair of early 70's small tripod mirrors that I would like to mount on my new aftermarket doors. The doors are already painted so welding is not an option. The doors came with no provision for mirrors at all: no holes, no braces, nothing. To mount these tripod mirrors and avoid ripping my door skins off, what should I do?

I've heard of using Riv-nuts or something similar, but that seems like it would place a lot of stress on the skin of the door, even when just adjusting the mirror. How could I mount these mirrors correctly and in the most durable way? Does anyone have some pics of the factory mounting setup? Thanks!

Hi Steve,

Dad's 77 GMC came with these RPO DG4 tripod mirrors from the factory:

If this is the style of mirror you have, they were originally installed using 1/4"-20 "jack nuts" with a rubber type coating to protect the paint. Just like the one shown on the left side of this pic I snagged off the Estco Enterprises website:

The originals didn't use any sort of bracing on the inside. But if your aftermarket doors have thinner skins than OE doors, you might want to consider adding some backing plates or flat washers to the backside of the doorskin at each mounting hole location before installing the jack nuts. Using some sealer to keep moisture from getting in between the door skin & backing plates or washers might not be a bad idea either.

on my 79 they are mounted with a nut that is attached to a giant washer that is epoxied to the panel

Sounds good guys, thanks a million! These should look good on my 83 I think. I always liked these style of mirrors. I may have the only 80's truck with these mirrors, 9 inches of lift, and a cap I've ever seen!

I have used the the same nut inserts that Ray_Mcavoy shows in his post with good luck, they can be a little tough to seat in the first time if you are not careful.
