Mustang Brake Booster Problems

[sj9ers]

Hello. My 1969 Mustang's power brake booster was bad and I needed a new one so decided to perform this swap with a fox body brake booster Fox Mustang Power Brake Booster Install . The article was for 67 and 68 mustangs but I figured it would work on mine. I got everything mounted and installed but the brake pedal push rod is way too long and its pushing the pedal very far out and the top of the brake pedal is hitting the clutch pedal rod. Does anyone have any recommendations on which of these adjustable push rods would work the best to shorten the push rod length if any
Heres some pics

With Clutch Pedal out

Theres about 8.5 inches from the pedal to the floor without the clutch pedal
