You might try ebay, some of the sellers listed to the left break up these kinds of sets. Short of that you could try removing the dye (Rit has dye remover that's easy to use) from a good set of 3-color BDU's then dye them your tan color. It's tough to cover a camo pattern, it really depends on how well the dye is set in the fabric. Also Dragon made a pair of plain tan BDU trousers as part of B-15C Flight Jacket and N-3B Flight Jacket sets. Atlantic Toys at http://stores.homestead.com/AtlanticToys/Categories.bok?category=Dragon+Carded+Accessory+Pack has the sets for $9.95 each. Unfortunately I don't know of anyone that's done the jacket except for TS.
