Speedway Motors 9166066 Details

This booster mount will make life simple on your old C-10. It adapts the original diagonal pattern on the firewall to a more common stud spacing that allows for the use of mass produced, less expensive 55-57 Chevy aftermarket booster/MC combos. Overall, less expensive than other booster master cylinder combos for 60-66 which require you to drill new mount holes and ignore the factory mounts that this bracket makes use of. 

  • Aluminum construction
  • 5.00" width
  • 4.00" length 
  • Natural finish
  • 0.50" overall thickness
  • 1.86" inside diameter

Worked great. This adapter bracket allows you to install without drilling any additional holes in the firewall...which means, if someone wants to return the truck to original, there's no damage!

The product and included nuts and bolts are flawless and fit is perfect. Problem is that this kit does not include any installation instructions. Considering the installer is using this kit to modify critical stopping system, the brakes, I would have appreciated having detailed installation instructions/torque settings/and those little hints on how to make the installation easier (such as leaving the mounting bolts loose until all related parts are installed and aligned). Regardless, installing this kit was not rocket science and any experienced mechanic should have no trouble figuring out the orientation of the adapter plate and how each bolt/screw connects. One question regarding the included fasteners--Nuts and screws are stainless while the four studs appear to be standard bolt steel. The question is why aren't the studs also stainless?
