Help bagging a 1950 chevy deluxe

hey guys,
so I know there are already some threads on the subject but here goes anyway because I haven't really been able to find exactly what I need. I want to bag my 50 Chevy, the car is all original and would love to keep it that way, I would hate to start cutting into it just because it is in such good shape with no rust.
is there a set up I can use that is just bolt on? maby some mild welding required at most? i know there's gotta be some guys out there that feel the same way and you just don't want to cut up your cars.

common guys help me out, show me the path, links would be great or what ever info you can hand out

 

here is an old article that i used from low rider magazine.
