Racer, I am a more current builder, with some twin I beam experience. I noticed that Tiny would not answer the question on what hotrod he was building and that is an important part of the equation. How wide is your vehicle? When I was way younger I put a '73 F100 Twin I beam front end under my '47 Ford truck. Things were looking good until I put the fenders on. The narrow stock wheels stuck out through the fenders a wee bit, Sheesh. Also the steering box pointed at the corner of the cab and was quite close, [really hard to get the column moved over that far to hook it up]. I gave up on that project.
After that I started on a '36 Ford truck. This also has a Twin I Beam under it. The secret of its success is that I used a Ford Ranger frame and front end. ['36 Ford truck on Ranger] on this forum. The Ranger is a way narrower and the steering box is up at the front of the frame. I have driven this truck around for a few summers now and it is a delight to drive, but I might be biased a wee bit. Good Luck.
