spring clips

hey guys, I need the spring clips that hold the interior "wheelhouse cover trim" on. ( long s.s. curved pieces in fastback) they have a 3/8" x 5/8'' head with the spring wires coming out of the middle of them which are 5/8" long also, instead of on the end like door panel spring clips. they also have foam rubber on the head of them I need at least 12 to 15 of them. -any help would be great!
thanks, -bob
