rear leafs 68 barracuda

It's normal. My 68 and all 67-69 Cuda's I've seen are that way. When the cars were designed they were designed around using short 14" tires that were so small you could barely tell they were not centered. Add bigger tires to the mix that barely fit the fenderwell and it is then very obvious. I made some plates to bolt in between the front spring hanger and frame to move mine back some. When I get the money for a new longer driveshaft I'll be installing them.
