The problem is that who ever did previous work on it over tightened that bolt and now it has cracks in it. It's not broke out, but I don't really want to put it back together like that. If it were to breakout while on the road, it would pump the oil out.

My question here is, has anyone had to deal with something like this, or if I could I would buy a new one, but I cant seem to find any new ones

Thanks in advance!!

There aren't any new ones available. What you're describing is a common problem as people overtighten the oil return pipe and it cracks the spokes.
We do the crack repair on those covers as finding a crack free one is nearly impossible after 92 years.
