A direct replacement for the breakage-prone stock plastic spacer, the billet aluminum MM Pedal Box Spacer mounts between the pedal box and the firewall. Ever notice small, crumbled chunks of black plastic in the driver's side footwell of your Mustang? That would be pieces of your aging stock spacer. Breakage isn't surprising considering Fox Mustangs are now between 25 and 39 years old. We all know old plastic tends to get brittle, and even a careful person may find the original spacer broken after removing the pedal box. Not surprisingly, Ford made the spacers from steel for the SN95 Mustang, and they are now an integral part of the pedal box instead of a separate part.

The robust MM Pedal Box Spacer is located between the firewall and the pedal box. It's secured by the same four studs that pass through the firewall connecting the pedal box to the vacuum brake booster (or manual brake adapter block).

Why would I ever remove my pedal box?
  • During a conversion to manual brakes.
  • As part of a restoration.
  • To swap between an automatic and manual transmission.
  • While converting to the later model Hydroboost power brake booster.
  • To replace a damaged spacer that someone has unskillfully modified to install an SN95 vacuum brake booster.
