What's the factory rear view mirror size?

[PhotonFanatic]

Hi all, I got into the old 87 R10 today and the rear view mirror was laying in the floor. I guess the glue just finally gave out. It's not the factory mirror, someone had installed some 1980's (or maybe 90's) upgrade with little switches and dials on the mirror. Never used them since the power wire was unplugged and I didn't care to figure it all out.

I'd like to replace it with a simple factory sized mirror. Is there perhaps a kit that comes with everything, including glue? It's odd that I've never bought a rear view mirror before, or installed one. Just never needed to. Any recommendation would be greatly appreciated!

The mirror in my 79 K5 is 10" and I think it's the original one.
LMC has replacement mirrors in 3 different sizes and glue.
The OER mirror looks nice but is pricey.
Mirror glue kits should be available in auto part stores for cheap.

Thanks!

Anyone know if they're for sure 10" from the factory?

I know this is a couple of months old but did you get an answer on the size? I got a 78 that I can measure.

It seems to vary. Some of the trucks had 9", and others had 10". Depending on the truck, some even had bigger but they were work trucks of various types. I went with 10" and it looks fine, it looks like the right size.
