Does anyone have any specifications of the length of each leaf for the Front Tapered spring on the 1909-1915 seven leaf springs? In searching for extra leaves, I am finding no consistency. The measurements I have on my 1909 Touring (not sure if original) are as follows, measuring in a straight line from outside to outside:

1st = 33 1/4 main leaf
2nd = 31 1/2 not tapered
3rd = 28 1/4 tapered
4th = 25 1/4 curled eye
5th = 21 1/4 tapered
6th = 16 3/4 tapered
7th = 12 1/2 tapered

Maybe there were various manufacturers making at different times, but Ford should have had specs on them, I am guessing.

Benson Ford Research Library would have the prints on each leaf, but getting there now isn't possible due to china covid. Mail requests are slow too.

Haven't seen any ref. to factory specs on spring leafs. But long ago a poster put this together from springs sorted and measured, but no taper leaf in this ref

7 leaf Model T Front Spring (1920-'25) - Measured Length of Spring Leaf and Overall Height of Leaf lying on flat surface.
9-3/4" -- 3/4"
13-7/16" -- 1-1/8"
17-7/8" -- 1-5/8"
22-5/8" -- 2-7/16"
27-3/16" -- 3-1/8"
32-1/2" -- 3-7/8"
33-1/4" -- 4-11/16"

This photo compares some various from Model T springs, and the second in line from the front is a typical taper leaf front, you can see the top leaf is longer than later clipped end top leaf that are short about 9 3/4" long.
