Try your local wrecking yard, that's whre I go first. Good luck.
They can be welded. Any welding shop can do it.

Mine looks like this so idk if that’s fixable or if it’s even a worry yet but once I know about something I can stop thinking about it lol

I'm not sure what year that bellhousing started but it was used at least from '73 to '84, they aren't a problem part so good used replacements should be easy to find.

The only aftermarket replacements I know of are race certified units which are expensive.

Ouch looks like someone ran over something substantial that hit the pan as well, might have broken the seal on the pan gasket might explain all that wetness on it and the front lower section of the bell. I would tear into that as well while I was under there.

Ebay would get you a good deal I think they used the same bell on the 3 and 4 speeds in the cars as well there are 2 versions If I remember correctly one with z bar mounting boss and one without, bolt patters are the same.

The wetness is from a substantial power steering pump leak lol I have addressed the leak just haven’t cleaned it up yet but im working through one small pain in the butt at a time lol

I’d appreciate that I’ll check on shipping how much would you want for the bellhousing itself besides shipping
