Those are very close in Comparison, But My kit box ,and instructions all say. Mine was supposed to have them. The rear of the box shows them illustrated next to the chrome parts.
I just received my order from Ed, at drag city casting. He let me know that the Lincoln tires, steelie, and artillery wheels. are no longer available due to the mold being worn out.
Heard a Rumor years ago, Mobius was going to do the same concept, that was done with the Ford Pickups, and apply that to the Chevy's, 67 to 72 short, and long beds. Now would be a Great time to unveil something New like that.
I think it may be suited for 50 & 60's era pickups. Not sure about the 70's. sure would be nice though. There is a Tutorial on FB, on how to fit the Foose Chassis to a 53 ford, and it touches on Other types of trucks, the chassis could be used for, as it does have some flexibility for other applications.
