cylinder outside dimension 70mm
rod dimension: 35mm

The open and closed lengths "you" need will be determined by the cylinder mount on your kingpost carriage.
The original cylinder dimensions may not be appropriate.

Also, you need to compare the system pressures between the two machines to see if the original piston diameter will give the appropriate force.
