You have a stock master cylinder pushrod? Do you have a stock master cylinder?
Seems with those, you could figure out what the needed length from the pushrod seat on the factory master to the brake pedal is and make sure your pushrod is the right length...then compare to the new master and see whats different...
If you dont have a stock master, maybe someone can measure one they have...
Id hate to see you cut that rod in error too...
Lord send your Holy Ghost into our hearts and make the desire of our hearts Your Will.
