Which 1500 series? P1500 (Step Van) series did use the Eaton rearend. As far as I can figure out and what I've seen the majority of 62 1500 series pickups used the Dana 60.
I'll re-quote,

Model 1000. Standard SM318 trans. Standard Axle H035. Ratios 3.07 and 3.92 available.
Optional trans 177 CA HYD. or SM420.

Model 1500. Standard Trans SM318. Standard Axle H052 Ratios 4.56 and 4.10 available.
Optional Trans 300GH HYD and Sma420.

Model P1500. Standard Trans SM318. Standard Axle H055. Ratio 4.56
Optional trans. 210U HYD

Model 2500. Standard Trans SM420. Standard Axle H072. Ratio 5.14
Optional Trans 300GH HYD.

That's what the 60-61 manual says anyhow.
