94-present Dodge 4x4s used coil springs & control arms instead of leaf springs; if you have fabrication skills or know someone who does, this would be a welcome upgrade from leaf springs (somewhere around 2005-ish Dodge switched from Dana to AAM axles, and the driver's side axle tubes are known to bend under hard use). BUT, the differential is driver's side, not passenger-side like pre-1993 Dodge trucks, so this would necessitate a transfer case change to a Ford-type or post-1993 Dodge TC. Otherwise, look for 1993 & older trucks for donors.
Also, even though D60s from GM products may look the same as a similar-year Dodge (or Ford with the pumpkin on the opposite side), the hub openings are NOT the same...Ford & Dodge use larger hub openings than GM. If you get a GM-sourced D60, any wheel's hub opening should work on it; but if you use a Ford or Dodge-sourced D60, only wheels meant for those 2 trucks will fit, GM wheels will NOT fit over the hubs unless you (or someone else) enlarges them by milling and/or grinding. Which is something else to look for on used wheels, and maybe even the hubs on used axles as I've seen a few that were "modified" like this.
As MatthewH points out above, try to source same from same: try to find a D60 front axle from a similar-year Dodge truck, as the spring pad measurements & widths will be the same, you have a better chance of finding the same gearing, etc... They are out there.
