Assuming the threaded bush is still captive and all you've done is strip the thread, you should be able to repair it with a s/s thread insert. These are marketed under various names, Helicoil being one of them.
The kit comes with a thread insert to the finished thread size/type you specify, a tap and an insert tool. You simply drill the old thread out to the EXACT specified size, tap it with the supplied tap, and then insert the new thread unit. It's a very cost effective and neat repair.
