I agree, that link doesn't look correct.
I was planning on just making my own. It shouldn't be that difficult for '41 & 42 trucks. I will need 2 for sure maybe even 3, so I am going to try it myself. The money that I save can be used on other parts.
On the other hand, my goal is not original-like restoration, but more rebuilt in an orderly way. I want to drive mine, and use them as trucks.
