Leaf Spring Suspsension - 1964 Valiant

A spacer is not a good fix for this as it will move the tire and the whole rear axle back in the wheel well of the body and it won't look right. This does remind me of when I accidentally put a body Springs on a b-body. They were an inch too short and they did the exact same thing. From where did these Springs come?
I wonder if you were to use elongated shackles if it would help.
