I'm thinking that a bracket similar to those that mount a booster and dual master on a pickup would allow doing the same on the bigger trucks.
Might need to custom fabricate the bracket.
Then I plan to use a bigger booster and master from a C60 or similar truck.
I'm some research short of starting this, but I'm hoping to approach it that way.

It's true. I really don't do anything but browse the Internet looking for trouble... | | |
