Is there a business that deals in parts for molds? I have a nice old Thompson Center single cavity maxi ball mold that needs a handle screws, spruce plate bolt and spruce plat bolt keeper . If you know of a company that deals with this stuff let me know.

In lieu of finding someone who supplies these parts for that particular mold you could always go to local hardware store and find like-threaded bolts/screw and trim to size.
I have one of Brownells’ firearm screw kits and was able to use of of those to replace a locking screw for an old mold of mine pretty easily.
I would guess that is not to be found. It would not take much to re-thread a near size screw to those if you could not find some. The mehenite is fairly soft.
Anyone know what size tap to buy to chase these threads for the sprueplate bolt? If I can get these threads fixed I’ll just use regular bolts I guess.
............When I was doing custom machine work I'd get quite a bit of action from folks with twisted off handle screws and wallered out (Technical term) other assorted mould screws.
Other then the SP screw, the others could readily be handled yourself so long as a person had the right bit for the required replacement screw/bolt.
Without a doubt, THE MOST IMPORTANT screw is the SP pivot screw. Get it wrong (tilted) and your mould will still be useless. If the mould wasn't expensive, then give it a try yourself. Just be careful and it could come out okay.

Are the threads in the mold damaged?If not take the mold to real hardware store and find something that will fit.It is possible that the molds were made by a mold maker like Lyman.
