hey duane, you might try sams offroad in tulsa. they are a pretty big shop, [i think they have one in okc too], i have seen them set up at a few of the larger local car shows. only thing is, i think they are into rock crawlers,[i e jeep], but they may have some broncos too. i think they have a web site but i am not sure. if i can find one i will send you the addy.
