Im not sure exactly what screw you stripped but your best options are
A. Buy the next size bigger (wider/fatter) and retap the hole the right size.
B. Shoot some JB weld into the hole and assemble it and let it set. May be hard to take apart after but it is and option.
C. Get a local machine shop to make you a new peice (prolly not cheap)
D. Fill the hole with jb weld or have a welder heat metal and melt it into the hole redrill and tap the size you need.

Option B is likely the easiest and cheapest way.
A would be the correct way aside from replacing or fabing a replacement.
D is prolly not cheap either and is kinda goofy unless you have the tools/skill to do it yourself or a brother/uncle/dad or someone who would do it for you otherwise you may as well pay to make a replacement.
