2extreme,
First of all, your name scares me, but your approach to building your truck scares me even more.
To ease my mind, please explain to us what kind of build you are planning on, and what your building experience is.
Before you consider cutting out components, you need to have a plan as to what you will be replacing these parts with.
What kind of brake system including the pedal are you using (original or custom drop-down)?
What will you use for a parking brake? (lock, as I understand them, is not an option).
Please don't be offended by my words, as none is intended.
Welcome to the Bolt, BTW!
Carl
