I just dropped a EFI 426 Hemi into my Challenger and I need to get a 8" or smaller power brake booster to fit beside this massive beast. Unfortunately finding one of these is proving difficult.
Have you tried MasterPower brakes or Stainless Steel Brakes Corp. another is G&D musclecar parts and Ted Stephens of Stephens Performance. Tonys parts may have it but beware, he thinks his parts are "gold" and prices them accordingly and they are in shoddy condition. Any pics of this car?
