There are tons of Mustang II crossmember setups for bags. If you want to spend a bit more and get a custom setup One of our members turns out some fine pieces. http://www.industrialch***isinc.com/ No Limit can build you a good setup http://www.nolimitparts.com/ Scotts Hot rods also has a good setup http://www.scottshotrods.com/ Then there is Art Morrison who's new shop truck, ch***is and photos of their crossmember kit for AD trucks is in the Dec 2012 issue of Custom Cl***ic Trucks with the Green AD truck from Oregon on the cover. Other than that it is how much you want to spend as some of the above mentioned ones will run up to 3k and a basic name brand bagged MII style crossmember setup will start around 1200.
the end result im looking for is running boards on the ground, if my budget allows. but would settle for lowering at least four inches
