Is there any way to lift the rear of a 66/67 to fit in bigger wheels and tires? I am wanting to go for the hot rod look slightly similar to the pics below. There are pics of Riviera's sporting 20 inch wheels or more so I'm assuming it is possible. I am unsure how its done and if air shocks, springs, coils will work without damaging the vehicle any. Looking to spend around 500-700. Less is better.
