Just in case you don't get the info you need from CPP. I have a complete spare front axle from my '50 truck here in my garage. Let me know if you need the bolt pitch measurement from it to compare with what you have on your '38.
The spare axle I have was working on my truck with the CPP Saginaw P/S kit; I only changed it out when I fitted new king pins and bushes to another identical axle.
