I don't know for sure. I know that a lot of people have used destroke's mounts on the super duty conversions, which I think come from auto world, and most report good success. You might check to see if they have anything for the OBS Fords. If I could move things along a little faster, where I could test mine, I would build you some or send some you patterns. I want to be sure they work like I think they should first though. -Nicholas
