Baddog Rails are great and well worth the money. They will help stiffen up your chassis as an added bonus. Be sure to keep an eye out for rust, nab it early, there aren't any "rust-free" z's that haven't been fully restored. For every inch you can see coming out of the paint, expect the amount underneath to be double, sometimes triple in size. Doing a tune-up (i.e. oil change, fresh fuel, all new filters, spark plugs, etc.) will go a long way on these cars as well as give you good time to inspect. Good luck and post some PICS!!!! :D
