I used a Super 88 Diesel engine in the restoration of our 1950 &quot;88&quot;. When depressing the clutch pedal, the fork appears to hit the fingers on the pressure plate before releasing the disc all the way. It will release enough to shift the transmission but have to grind gears if stopped. Is there a different length throwout bearing carrier between the two? Also, the clutch adjustment is at the end of the threads on the pedal rod.
