For a replacement rack for the '33 hot rod, there's a lot that needs to be known to be able to order a better replacement

Start with this: define an imaginary line from your upper a-arm pivot to your lower a-arm pivot on both sides of the vehicle. This represents the location of your inner tie rod pivot joints while steering straight ahead. Then of course you will need to select your steering ratio unless no options exist. Also, you obviously need the steering shaft to line up with the steering input shaft. All that’s left is the mounting setup and overall width between outer tie rod ends.

I’m assuming that you are using a rack and pinion setup and that the mounting points on your chassis are already there, establishing the centerline height of your unit.

Why do you not call Maval manufacturing in Ohio and order a rack. I believe their aftermarket division makes the racks for Factory Five.

What problem are you trying to solve? I’m not sure the rack is really a source of issues. Upper and lower location and the alignment impact loading on the links to the tie rods. The geometry of the input ujoints is really close (over?) the limits of the joints depending on tolerance stack up. I think the rack itself is ok.
