They dont have the rubber O ring that goes on the crank case below the cylinder in stock. Does anyone know where I can get this? There is also a tiny rubber O ring that goes on the oil port in the crank case that the cylinder sits on? I cant find that either?

I bought This ebay kit and it had the orings you're looking for. It's a complete kit so it'll have everything.

Check with local hydraulic repair shops, or bearing suppliers, or even machine shops.  Bring your old ones in and they can likely match them up for you.

You might have to buy a minimum qty if it is a size they need to order in but it should still be cheap, likely less that $5
