This is the clamp-on bracket I designed for my Mustang II 3 link, but I am contemplating switching to a torque arm similar to what you have sketched and then using the front leaf spring hanger instead of building a whole new frame. The axle bracket would be the same either way.








How big is your rear end tube OD?

EDIT: Sorry, I misunderstood, I thought you were talking about the axle bracket. Why not use the existing leaf spring pocket though for the lower control arm front attachment?
