I am working on restoring a 1953 Commander Hardtop Coupe. I have heard the frame on this car referred to as the "flexi-flier" and so I wondered ifanyone had any experience in stiffening the frame on these cars. I am planning on a V8 with about 200 HP and an automatic OD transmission. I plan to keep the stock rear end which is a 4.55. Since I have the body off, now is the time to work on the frame. I have seen several people that have worked on this vintage of Studebaker and the frame mods range from adding a straight cross member or 2, to much more involved "X" frames. Some of them seemed like extreme overkill. Any recommendations will be appreciated.
