Look on the axle for the DANA ID tag. I would think the code would be universal.

Slow down there young fella,
Let's see if U can ID the rear end gears by the method described (mark the tire, rotate the d. shaft). It will tell the rear end gear. Let's go from there...unless U got lots of money or spare parts.

May have an NP 435 and D 70 (? gear seems to be 410?). Now how to tell him if it has 2 speed rear end?
The quick change in the final drive ratio (tires) aint easy w/6 of em on the ground.
When is this trip planned?

Two and a bit for one turn of the wheel, and number of turns of the driveshaft for two turns of the wheel. Sounds like 2.1 DS turns = 1 tire turn, or 4.2 turns. Sounds like a 4.11-ish.
That'd be my guess anyway.

A 4.10 rear, with a direct high gear, would yield between 2600-2700 RPM @ 100 KPH (62 MPH), depending on overall tire diameter.
110 KPH (~70MPH) would put your engine just about 3000 RPM.
Hardly screaming, but just sounds that way.

Now how to tell him if it has 2 speed rear end? ("first, I don't use it at all. Second is 20 mile's max scream. Third is 40 miles max scream. And can't screaming any faster")
A D70 Could Be a two speed, no? Altho it is a table top (our "flat bed") now it could have been a dump at one time. IIRC we had 2 speed rears in em back then.
Hey, Patrick, does it have a line runnin outta the rear end housing (or the remainder of 1)? Here we had a switch (red 'button') on the transmission shift stick we could push/pull to add a lower/higher gear to the rear only.
