would i be able to just get that side of the case or do i need to buy both sides?

Depending on what the case is made of you can try having it welded. You’d be cutting it close but it’s worth a try.

I have seen that very area JB welded before it works for a couple of days and then it starts to fall apart after riding a while. Welding it with a Tig welder and some aluminum rod is the only way to weld that but in order to weld it right you would have to take that casing off anyway. Pretty much have to get that casing replaced. That means taking the whole motor apart looks like from the parts Diagrams.
