Stock front axel on a K20??

[FLYNAVY30]

As I'm slowly plotting the eventual conversion of my C20 to 4wd, I've started compiling a parts list. At the moment, I'm leaning towards a Tremec TR-4050 manual 5speed with either an NP205 or Atlas transfer case. Ill probably use the B-52 mounting kit and spring from DIY4x for the front springs and retrain the stock Dana 60/trailing arms/coils in the rear.

My question is, what was the stock axel set up on the K20's and is that the best option for this application, or is there something from another year/model that would make more sense?

This thing isn't going to be a rock crawler, just a daily driver that I can take camping on trails and in the mud...and the big reason for the 4wd conversion, is so that I can pull a boat up and down the steep boat ramp at the end of our street.

Thanks for the input!!
