Repair sport mirror base?

[Mountaineerfan 49]

So my passenger side sport mirror base cracked and broke between the mounting hole and the stem. Would it be possible to put these parts together with some solder or some JB weld reinforced with a piece of metal? I really don’t want to buy a new mirror and then pay to paint it. If I could find a base that is Acapulco blue, I could just replace that.

I would rough up the back side and use epoxy with some wires embedded to try to fix it

I tried this exact method with a broken shaker ring without luck about seven years ago. Then I tried Steel Stick from JBWeld which has held up since then.

The steel stick epoxy I would say is a good choice

I'm picking up some Steel Stick this afternoon.  Last night I taped the "pretty painted side" of the base together, and on the inside put a coat of traditional JB Weld, a small piece of metal across the seam, and covered with more JB Weld.  I've left that to cure for 24 hours undisturbed, and when I get home from work I will put a layer of the Steel Stick over it to reinforce.

Broken Mirror

Here's a pic of the break.

UPDATE:

I'm cautiously optimistic.  

When I got home from work last night I took off the tape and checked the cured JB Weld.  It seemed pretty solid.  So I took the Steel Stick and covered over the JB Weld and extended it up into the base recess and let it setup for 5 minutes.  I then attached it loosely to the car, waited an hour and then torqued down the screws.  The mirror seems more solid than before, and I opened and closed the door a few times to check for any movement.

Today I drove the Mustang to work and the mirror stayed rock steady the whole way.  I'm pleased with the repair so far; the crack is barely noticeable, though if you run your finger across it you can definitely feel it.

I had ordered a replacement mirror from NPD which should be arriving today.   My plan was to return it if this worked, but I may hang onto it as an "in case" so I have a backup to get painted if my repair fails.
