I have a '54 stick shift changeover less transmission, but I prefer not to break it up.  Even have the shift rods from the column to to transmission, no column.  But, if the pedal assembly is worth enough to you, I'll sell you the kit.

I did not know that Carl was trying to deal with you, I will back off until you and Carl work things out.  I believe the '55-'56 equalizer from the frame to the engine is shaped differently to clear the left exhaust pipe on dual exhaust cars.  '54s didn't have factory duals.

I checked my stuff to make sure everything is there.  It isn't.  I have two clutch pedals and arms(??), a brake pedal, the clutch linkage except for the spring from the throwout arm to the frame, and the bracket that bolts to the engine and supports the inner end of the equalizer.  I do have the heavy under dash spring and the adjusting J bolt, and the torsion spring that returns the brake pedal to the top.  The '55 stuff Carl has will also fit, and again, I won't horn in on Carl's deal, he was here first.  I seem to remember something being different between the stick and auto brake pedals, beside the wider pedal pad.  Something about the pedal pivots.
