Model T "Tub" Stock Wide And Length (What Is It?)

I've got left over tube from another project, and I want to build a Model T frame for a buddy's birthday. I don't want to ask him what the width and length of the tub is because he would put two and two together. So I guess a better question is what is the stock frame length and width of a Model T frame and tub? His is a '26-'27 style tube.

 

On a "T" frame, the overall width is 23" and the wheel base is 99.5" - 100". I have seen some variation on that one before. Wescott's has a ch***is diagram in the back of they're catalog and I ***ume on they're web sight.

Thanks guys. I'll get right on it. Can always count on you's.
