Does anyone know if there is available a larger diameter swaybar than the one that comes with the V8? Also, is it possible to remove the front sway bar, as it snakes through the chassis- how would you get it out?

You might check if SEC sway bars are thicker.

To replace the front sway bar, everything attached to the bulkhead has to come off. In some cases the engine has to be lifted a little.
