You just have to check the bolt pattern.
As long as the bolt pattern matches your inner primary you are good to go.
I had a 5 bolt derby cover but a couple of the bolts were stripped and I got a regular one from a friend of mine.
No leaks on either one.

Yes. The 3 hole warps and it leaks. But I was told I would have to change the inner primary, and then I might have starter issues too. So I mop up every day. But I was noticing when I was at the car wash not long ago, that it looks like the inner primary is leaking around the solenoid/starter, whatever that is with the jackshaft. Whatever, it leaks.

I use the 3 hole gasket from Harley. If you are using the O-ring that may be part of it.
Sounds like we have another project here!!!!!!!!!!!!!!!!!!

I use the paper disc gasket. They sold me an o-ring too, but there is no way I can get the thing on, so it went in the trash, just like the oil filter o-ring they pushed on me...don't use one. Anyway, torque is the problem. I just use a driver and tighten it by hand. Another project? Been there, done that, done with it! Doesn't stop it from going down the road.
