So, I was futzing with the cleats on my Answer carbon road shoes. The bottoms were caked in mud, and I think a bit of it got on the threads of one of the cleat attachment bolts. When I tightened the cleat bolt down the threads in the plate inside the shoe (into which the cleat bolt goes) stripped.

The plate is a funny shape since the shoe accepts Look, SPD and other cleat types. The holes I am using are indicated in red in the picture. (see attachment).

I am using a SPD cleat and there is not another set of SPD holes that I can use on the plate. Also, these shoes are basically extinct, so I doubt an exact replacement for the plate is available. If this were a mountain-type SPD shoe with 4 mount holes, I would just move the cleat to the other set, but in this case it seems like the only option is to switch to Look cleats, which use entirely different (and hopefully intact) mount holes. I don't want to buy new pedals and cleats because of this.

Having said all that, is there any way to repair this mounting plate?
