I have my Mk IV go-cart running but would like to adjust the clutch pedal height for a more comfortable transition between brake and clutch. The engine, trans, clutch are out of a 2001 Mustang SVT donor. The picture attached shows the current position of the clutch pedal. Factory Five says it should be about 1/2" taller than brake pedal. Right now it's about 3". What's the best way to adjust this? Thank you.
