1965 Window Motor Stripped screws - how to repair

[jj_sharp]

Two electric window motor screws fell off from the window regulator, and there is at least one stripped screw.
What it my best bet for fixing this?
Not being a proper mechanic, this leaves me scratching my head.
If possible, I would prefer not to purchase parts.

1. Drill it out, and use a nut & bolt (not sure this can work).
2. Tap to the next size (not sure this can work).
3. Some sort of JB Weld solution (maybe fill & re-tap)?

Thanks for any advice that you may have.
I am going to study it some more now, will check later for any advice...Thank!

My wife has put maybe 200 miles on the car, I expect much of this kind of thing going forward.

I swung the bat with a 1/4 x 20 tap.
Not sure that that means, but I plan to run the screw all the way through the hold and MAYBE put a nut on the backside.
It makes the housing look a bit thin, time will tell if this was a good plan OR not.

My Wife's car window is fixed.
I learned a bit.

I think the 1/4 x 20 tap of the stripped holes might be pushing the upper limit for size, but I tapped it and it worked.
The idea of the nut on the backside failed (had to cut the extra part of the bolt flush with the gear housing.
