Good to see another one from Mn on here. Check some of the parts suppliers like American Classics link on the top of this page. You will find there are several options for going disc up front.

I don't know about rear discs on a stock truck. One thought..you could go with a late model S-10 or Trailblazer rear. One of those would get you discs on the back end while changing your gearing in the process.
