Kevin I checked CPP's web site and it appears the spindles for C-20's all require swapping to five-lug brakes. And while lowering the truck would not be offensive to me, loosing the bigger brakes is not something I'm willing to accept.
I just Saturday attended a Ron Covell (Professor Hammer) Advanced Metal Working workshop where he showed how to make a fender from new flat stock. Based on that I'm feeling brave enough to widen a set of fenders to cover the wider front axle. And that is something I'd enjoy doing!
