Frame dimensions needed

I need some measurements.
Width of frame Model T.
Width of frame Model A.
Width of front spring for Model A, Model T and '40 Ford rear.
Good starting wheel base for A or T roadster.

I mocked up my Paige roadster last night and have some questions that need answers.
Thanks.

T and A frames taper over their length,but the bolt pattern is the same.A frames are heavier.
Wescott has dimensioned drawings in their catalog.
