Axle code missing! What should it be?

I found a 2000 F350 cclb dually for a parts truck. The axle code is blank on the DOT sticker. I hate it when Ford does that. Should I expect it's probably a 373 or a 355?

It's in another state.

The drivetrain will be for @calvinhg OBS, so I'm hoping it's 3:55. But because it's DRW, I suspect that 373 was the stock ratio.

have you looked for a tag on the rear axle housing cover? There is usually a metal tag under one of the bolts.

Got a pic of the axle tag but can't find a source to decode YC35. It appears to be 4.10 LS, might be a Dana 80.
606263-2 might be where it's built and when?

What do you think?

4.10 indicates thee gear ratio. I suspect it is a Sterling 10.5" rear.

If it were a locker, it would be 4L10.

You can compare the cover to these and determine the model of the axle.

I don't believe that Ford ever used the Sterling in a dual rear wheel application. It's in another state so I can't crawl under there and have a look, but I think it's probably a Dana 80.
