You're building a custom - essentially one-off - car, so you're going to have to figure out everything as you go along. That's a great part of the adventure, figuring out how to solve the various puzzles - no one's going to lay it out like a kit. I (and probably most here) don't know the Vodou design so we can't comment on what bushings they use or what you can use in their place. If these bushings are metal, maybe start here:

My advise is to read through the many build diaries here and see what others have done, as there's about a millions ways to build a car and they all work pretty well.
