The easy way to 'move' the clutch pedal is to pull it out (only 1 bolt), take an angle grinder, put a 30-45* groove in each side of it, bend it in a dogleg in the grooves and have someone weld them shut. (or if you have access to a press you can just bend it in that).
When you say the oil gauge has issues, what do you mean? The gauge/sender in fox bodies was more like a dummy light. It showed either no pressure or middle of the gauge. If it's showing nothing on idle and middle once you rev it up, it's just an old tired motor. Pick up a cheap mechanical gauge at your local auto parts joint of preference and slap it on to see what it's really doing.
