Headlight Placement

I started to mount the wings for the headlights on the bonnet of our TEA tractor, but I’m not sure what the original right position is. As seen in the drawings http://fergusontractors.org/nfs/ there seems to be no measurement for the mounting holes? Do you know the right measurements for the headlight mounting holes on TE/TO-20 tractors? March 06, 2015.

You are correct, none of the TE models had knockouts for mounting headlights. All TO models had knockouts until around the time the TO-35 became the MF-35. The MF-35 had removable plugs rather than knockouts. I believe the earliest versions of the headlight mounting instructions had the dimensions on the drawing. On the T0-20 the mounting holes are about 4 inches from the front (edge of grill) and 2 3/4 inches down from the top of the dogleg. (Where the dogleg meets the hood.) The holes are 1/2 inch in diameter and are 1 3/4 inches on center from each other.
