Where can i buy new aftermarket upper and lower control arms for my 2001 3500 4x4 long wheel base truck, went by the dealer and they are back ordered and not available, can i order these online anywhere??? I searched the records and all i saw is a place in Cananda selling some, who has b ought these lately and what did u pay and how are they doing?? Thanks, I am going to South Dak and just discovered I need new ones, i am fighting a terrible shake in the left drivers side even after new ball joins and track bar, I am going to buy all new tires and have them balanced in the morning and also get new Rancho shocks to try to cover this up if i am forced to go on the trip with the new stock or aftermarket upper and lower contol arms, thanks for any phone numbers or websites in advance.
