"I have 2 drawings of the front axle. One is dated 12/26/1916 while the other is dated in November of 1919.

The 1916 version says spindles are 51-15/16" apart with tolerance of +/- 1/8" while the perch holes are 36-1/2" with tolerance of +/- 1/8"

The 1919 version says spindles are 51-25/32" apart with tolerance of +/- 1/8" while the perch holes are 36-11/32" with tolerance of +/- 1/8"

I have no idea if it was different on the earlier axle or the later versions either."

This post discusses the differences in the Murray Fahnstock drawing and actual measurements taken by one of the posters.....

"6. I did a spot check of the touring body drawing on page 150 of Fahnestock's "The Model T FordOwner" which Tom posted above. I compared the drawing against what I believe is a mostly original 1918 Beaudett touring (USA produced). Only one measurement was the same -- the passenger front door opening was exactly 17 inches as his drawing indicated. The other 3 or 4 places I could easily check were all slightly larger than his dimensions with the exception of the distance between the body irons on the side which were 1/8 inch LESS distance than his drawing.

That may be caused just from the differences in the bodies (he even has 1/4 inch difference shown on his touring body at the rear width between the different bodies (i.e. that 25 7/16 or 25 9/16 measurement would be multiplied by 2 for the total width of 50 14/16 or 51 2/16 inches wide at the back of the touring). The differences in my body could also be due to wear and tear over the years, sagging frame, kids playing in/on the car (hey I was one of those kids a long time ago) etc.

I could also have misread or mismeasured the car or multiplied the 1/2 numbers from centerline that he shows (never do math in public). But on my touring at the body irons the rear top bow rotates he shows it 25 5/8 inches x 2 = 50 10/8 or 51 1/4 inches. Mine measures 51 13/16 or mine was 9/16 or 3/4 inch wider than shown.

The next rear measurement across the body from rear door opening to rear door opening he shows 23 5/8 times 2 for 46 10/8 or 47 1/4. Mine is 48 wide (measured at the top -- it gets smaller as you go lower on the body) so mine is 3/4 inch wider there also.

The next width location I measured from the inside of one front side body iron to the inside of the other front body iron. He shows 25 5/8 times 2 for 50 10/8 or 51 1/4. Mine measured 51 7/8 or 5/8 inch wider (oh -- and until just now, I never really noticed that I could push in on some of those parts and make the distances smaller by about 1/16 to 1/8 inch depending on how hard you push.

My rear door opening is 3/16 inch more than he shows."
