Do you have concerns because of rust issues, or because you question their strength with all that sheet metal removed?  If rust is the concern I understand, but otherwise there are alot of cars that are hella fast running the set-up you are planning on with OE rails.  If you are running bars from a cage down to the front rails thru your firewall even better.

 Ditto. If the rails are in good shape, use a front bar from the cage in side out to the front of the rail. You can mount the shock or coilover to this bar, and  if you think it needs more support run another bar down to the rail. Remember the rail is supported in two location by the K frame also. duster
