Now that I study the parts and start designing, I've concluded that if I am to adapt a K monlever etc. I have to either create steel mount point for the monolever pivots or my epiphany of the moment, TIG the carved up case mount points to an aluminum plate base that I then bolt to the frame. This would allow the aluminum monlever and steel frame to mate and be adjusted slightly as a unit for toe, camber, caster.
I still need to design a shock tower.
