Truck Arms Vs 4 link

[Ziegelsteinfaust]

I have a 74 C20, and want to upgrade it rear suspension at some point down the road. Especially after I figure out which way I want to take my project.

How hard is it to adapt the truck arm to the later chassis, and it worth the headache vs a parallel 4 link? Either set-up would have a long as possible track bar. I figure cost would be the same especially after modding the truck arm to fit. The front suspension will get the re-located A arm for better handling, and what ever in the rear to compliment it.

Current plans is to trim the height of the truck a bit, and level her off. I want to run 255/60 17's front, and 275/60/17's rear. So the trimmed height will be based off final tire height. Which will only be around a 1/3 drop which is what I am figuring now.

I went with a C20 for towing, and bigger brakes. So when I rent a camper to go fishing when my boy gets a little older. I have a higher safety margin.
