Light switch rod and steering box need help

[Vanspeed]

Hi guys, I have a question regarding early boxes and headlight switch rods. I am putting together a ford using a 1948 ford F-1 steering box. I want to run my 1935 banjo wheel and light switch rod on it. I have a spare tapered shaft because the F-1 used a splined shaft. I was told that using the bottom plate and associated parts off a 37-39 ford box will get me the parts I need. I found them but my headlight rod will not go through the tube in the bottom plate. Does anybody have a box taken apart that can show me what the bottom plate and tube look like from a 37-39? Does the bottom plate have a tube? I have one here from a 37-39 I believe and there is no tube. Very confusing.
