Got a suspension question

[fryer1979]

So I've tried searching a bit, and maybe I'm just not getting the right keywords in but I can't seem to find an answer to my questions. I'm soon to be taking on a 1966 LWB 2WD C-10 project that I would like to make into a daily driver. I plan on finding a '73 to '85 2WD to use for a chassis parts donor (to get power steering, disc brakes, and five lug hubs to mount the wheel set I already have). My question boils down to: which rear suspension is better for a driver? Should I hack the '66 mounts off it's rear-end and put them on the latter unit, or should I put the entire rear suspension from the later truck on to the '66 frame? As stated above the intent of this truck is to be a daily driver so a good ride is preferred. It will also serve duty as a pickup, hauling random this and thats with the possibility of some towing as well (although nothing heavier than a classic musclecar on a trailer, nothing a 1/2 ton truck shouldn't be capable of). Again, I tried searching quite a bit so I appologise if this question has already been covered. Thanks.
