'73 Honda CB/CL 350K4 Lower Crankcase Cover

I was wondering if anyone had any of these lying around that are in good condition? In trying to take the drain plug out, it seems the previous owner nearly stripped the threads, as well as damaging the plug itself. I can potentially repair the plug with some welding, but I'm not sure I can work with the threads on the case just yet. I'd like a backup just in case.

If possible, I'd love to find a lower crank case over and replacement drain plug.

Any help would be greatly appreciated!

Thanks!

Helicoil would do it i guess? Covers are hard to come by, all those threads are dead because nobody likes losing the plug, therefor they're always tight as fuck.
