Hi, guys...is it possible for me to transfer my brake pedal light switch, rod (little tube that connects to the master cylinder), and bushings to a manual clutch pedal assembly? or are they different sizes?...thanks

 

'65 should be the same size auto or manual. Only the pedal arm itself should be different.
While you're in there you should get the roller bearing kit. Makes the clutch pedal much smoother. If not use a High pressure synthetic grease to lubricate the bushings.
Good luck,
