Cracked another one. This one was repaired previous to my owning it. I put a 4 1/2 in. piece of mahogany wedged in just so but even with full adjustment its a BEAR.
I'm going to tear this thing apart .....soon.
If you go thru clutch cables and/or have trouble with your pedal being excessively stiff , can't keep it adjusted , etc..... check the pedal box on the far left for US cars and alike. Just below where the pin is for the pedal (pivot). Right where the cable mounts to the side of the pedal box.
Good luck with yours.
