Super C hydraulic leak

[Eric85]

Rebuilt the touch control unit a few years ago and the control valves have been leaking the last year or so.
Can I remove the control valves from the front and replace the o rings or do I have to remove the back cover also ?

Does any one have the part numbers or size of the o rings I will need ?

Incase anyone runs into this situation.

I was able to remove the control valves from the front.

The part number for the O-ring I need to replace is 350 672 R1
