F250's and F350's had standard 3.55's with an option of 4.10's. I remember the F Super Duty trucks having 4.88 and 5.13 gears ratios. But no 4.56 (4.55?) that I am aware of.

I could see it saying .L55, 98% of the time the first number is under the bolt head.
4.56 gears would top out at 65 MPH at 3300 RPM in direct drive.

I know you can get 4.56 gears for the Dana, and since the Sterling and Dana are usually off by just a little, I am going to say it is possible.
Or another possibility is the axles are both Dana's.
