A new Wagner 34403 Hydraulic Brake Master Cylinder that I got at an auction of vintage car parts.

According to my Wagner catalog, this is for the following models that use a 1 1/8" Master Cylinder:

  • CHEVROLET EL CAMINO TRUCKS  (1961-66: P13 Forward Control with Power Glide Transmissions;  1963 (2nd Design) -66: K14 and K15 4x4 Models with Flat Face Cowls and/or Power Glide Transmissions;  1963-66: C14 and C15 4x4 Models with Flat Face Cowls;  1960-62: KC14 and C15 Models with Power Glide Transmissions)  
  • CHEVROLET C25 and K25 TRUCKS  (1964-66: all C25 Models with Moraine Manual Brakes and Flat Face Cowls;  1963: Model C25 with Moraine Manual Brakes and Flat face Cowls;  Model K25 4x4 2nd Design with Moraine Manual Brakes;  1960-62: Model C25 with Power Glide Transmissions;  Model K25 4x4 with Power Glide Transmission)
  • CHEVROLET C36 and C38 TRUCKS  (1960-66: all C36 and C38 with Moraine Manual Brakes)

The box is very rough.
