Drilling my Zbar??

Quoted: (A-Body, all you need to do is cut and extend the arm at the rear of the pedal (the arm connected to the torque-shaft connecting arm). If you increase the pin-to-pin length to six inches,) 5 1/4 is stock. Measure yours and see what you have. Anyone know the length on the Brewers ?
Mine is 5.25" but having the pedal 'welded in' by previous owner (smh), I have decided to mock up a 6" with some flat stock steel I have and secure it to that existing arm. At least then I won't butcher anything and can see how much improvement it will be.
