Hyd pressure and volume on a C

I have a C that I converted to 3PH using the touch control. I also have the line and aux valve setup from a Super C that I can install. My question is how much pressure and volume does a C have? I think I need to use the valve and line set that I have from a Super C and use a hyd cyl to make the 3PH work slower. Right now it is way to fast and I'm afraid I will tear something up when the lift drops and raises so fast. Does any one have a close up picture of how the fast hitch on a Super C looks and how much travel the cyl has? I realy appreciate the help given here and I don't want to tear the old tractor up as all I use it for is scraping my drive so buying a factory hitch is out of the question, but I am a decient fabricator and can build most anything I need. I hope the link to the 3PH works and you can see what I now have and what I think I need

I re read Kelly's how to post pics post and I think I have it now

The 130 and 140 have much the same idea on their fast hitch, two holes on that upright from the rear rockshaft, and one can use either hole depending whether speed or lifting power is required.

If you wish to go the external cylinder route all SC, 200 and 230 fast hitches had a cylinder with 3" bore and 8" stroke. Same as standard 3" implement cylinder. Again speed and lift will be determined by where you hook the cylinder to that rear rockshaft.
