Odds of finding an MK3 charger bridge?

Providing you've the required tooling:

If the holes aren't TOO far out of line, just ream the holes in the assembly oversize. Turn down a bit of mild steel rod and swage the ends. Dress flush. I'd use a rivet sweezer to minimize the possibilty of distorting the action body (it's not too hard to do damage here!) rather than a impact gun or hammer and bucking bar. But if you've no other option, it's do-able.

I'd probably limit the oversizing operation to not much more than 0.062", but would feel better at 0.030". (It's a stressed area, after all!)
