    Doesn't sound like it effects the McKinney adjustable saddles as they are set with a jamb nut once adjusted.

    Does anyone know if this applies to modifications? Specifically, we are mounting a newer body on our chassis. My thought was to weld mounts to the back of the main chassis for the structure that would then support the rear body pivot. Are we allowed to have this as a removable structure or must it be welded to the main frame?

    Did you ever notice how some cars have 3 in. clearance from the nose to the track, but at the finish line, the nose is rubbing the ground.

    My read is that the structure must me immovable and stationary during a run, but that's only me.

    Imagine what could happen if NHRA let off a bit? NHRA by the way stands for "No Hot-Rods Allowed".
