The guys at Jamco advised us that the brake booster/master cylinder/pedal portion of our disc brake conversion would not be a simple bolt-in swap. Still, they supplied us with parts-including a universal swing-pedal assembly-to get us started. Mounting the master and booster on the firewall just wasn't in the cards, so the swing pedal setup went in the spare parts bin. We were able to use the master cylinder, dual-diaphragm booster, and other brake components, though.
