Mocking up my 23 Dodge, but I think the frame is Model A. I'd like to run cross steer if I can pull it off. I thought about notching the crossmember and running the box through it. The box that came on it is junk I'm sure, but I was going to go shopping at the salvage yard tomorrow for something. I'd really rather not run cowl steer if I don't have to. Any Idea what this box is? Also don't know anything about the brakes yet either.
