So they make these things called helicoils for replacing threads. Basically looks like a spring coil and you drill out the stripped threads to a specific size and tap it for the outer coil thread, twist it in and the inner coil fits your screw. But yeah the repair costs as much as a new motor lol. Worth having the tools on hand though since the helicoils themselves are like a couple cents
