Wagner N-85 cylinder leak

[RMK818]

I have seen several posts about this but nothing seems to fit my situation so looking for advice and help. My steering is leaking fluid at the cylinder. I have checked to see if it is running down from any of the hose connections, it is not. I checked to see if it is coming from the the piston side, and that too is dry. It is dripping down from the mounting pad pin. If I have to pull the system out, what thread size is needed to cap the hoses that connect to the cylinder? I have put absorbent rags under the cylinder to help pinpoint the leak area, confirming my drip area. Thanks in advance for the help..

Update to my post. I pulled the steering control out and had a local hydraulic mechanic look at it. He said that it was a bad seal located in the rear of the clevis pin. Replaced all three seals and no leaks...
