1" bore MC versus 7/8" on the N/A MC and 15/16" on the TII MC. The idea is less pedal travel for a given amount of braking. No modification to the firewall but the N/A booster can't be used. I've read the TII booster can be used but I got the 929 MC and booster together so I used it. Just had to switch over the clevis for the brake pedal and modify the proportioning valve bracket a bit. IIRC, the N/A booster is a 8" single diaphragm, the TII is a 7-8" dual diaphragm, and the 929 is 8-9" dual diaphragm.
