This questions applies to Skymasters with engine driven hydraulic pumps

I need a hydraulic mule for powering the gear system on my ‘1966 337 during annual maintenance. Does anybody know of a good solution for this? I have seen “homemade” types and I am sure Cessna must offer something (for lots of money) I am just wondering what others are doing to power the hydraulics during annuals
