Theres no need to take the whole front bar off all that is needed is for you to go gumby with your arms and reach into the reo's,(thats the metal bar that the front bar is suppported by), support arms and loosen the back one and the front one on both of the supports that the reo has..
Get someone to lift it up to the right level while you retighten them back up again,wallah!!!
Jack the car up and work from underneath i think that it'll be allot easier..Make sure that you have somthing underneath the car just incase the jack gives way...
