I am not sure that you are reading my post correctly, There is no rear hangar to weld on or tack on. I am talking about the location of the tube for the shackle on the front springs. This is a bare frame that will be turning in to a formula toy. I do not have the axles or any thing else I just want to know the optimum distance between hanger and shackle tube. I am sorry if I am not being clear. I am still trying to decide where I want to put the front hangar, I may put it in front of the front cross member and this will determine how far back for the shackle tube. You can see the frame on my other post.
Thanks
