I need to adjust the clutch cable upward into the cab on my Case 2090. When the clutch pedal adjustment screw hits the firewall of the cab the pedal itself is hitting the rubber floor mat. I need a little more push on the inside of the cable so the powershift lever will completely return to 1st and the valve spool will extend outward fully. How do you get to the adjusting bolts/screws on that cable? From the bottom side of the cab all I see is a rubber grommet. From inside the cab when you pull the floor mat back there is just another steel plate. Looked at it quickly last night and I can't remember if that plate is removable or not? Appreciate any advice. Thank you.
