Clutch Housing 78mm

I have an engine bigger than 33cc. I believe it is a 77 or 78mm clutch.

I have looked all over and I found for $10 at Daves a clutch housing.

I also found the bell and shaft for another $15.

My question is , is that the best out there, I have had trouble googling

Clutch Housing or Clutch Drum.

There are very limited info out there. Anyone knows who sell dem drums for a weed wacker style engine?

THX BUT. I need the housing not the drum. And that drum is too expensive I hope people don't pay that normally or else I'm in the wrong business
