Hi guys! First post here. Just bought me a high-mileage 91 monty ls, and I love driving every minute of it. I like the bouncy seat! Anyway, on my front doors, there are tabs that I don't know what those are for. I don't think it's for side view mirrors because I do have the original side mirrors. Previous owner doesn't know what those are either. It's a clean install and it looks OE. Anybody in here knows? Thanks!

(Sorry about the pic going sideways. I don't know how to flip it. )

 

never seenem.
Extended towing mirrors??

 

That's what they look like.
