On a 67 GTX factory hemi with power brakes. Is there anything special about the bendix booster or is it just the brackets and linkage that mounts it that is unique for a hemi application?
 
3/8” mounting studs instead if 5/16”
 
Bolt pattern. Hope you can read it. Bendix booster.

The drawing is like looking at back of booster. The left to right are wider 3.5" Hemi. Non Hemi is 3 3/16". Top to bottom same on both boosters.

Thanks, I thought the mounting dimensions were different on the Hemi booster. Thanks for the exact specs.
 
mounting studs are 3/8" , non hemi is 5/16"

Also, the arm that come out the back side has a different shape than non hemi versions
