I believe the stock drum brake spindles are different between the series.
If you were thinking about going disc brakes, now is the time to do it. If you're planning to stick with the drums, you can check with Aspen Auto (
https://www.aspenautoaz.com/) or you could become a subscribing member of the site and post a WTB on the parts section.
The stock drum spindle for a 1/2 ton is the same from 63-70, so availability is fairly decent with all the conversions to discs
