Since your conversion was for a C10 and the subject of this discussion is a C20 there could very well be some differences.
However, it sounds like a great opportunity for you to write up a "Tech Tip" for the bolt in conversion of a 97 Suburban rear end with suspension to 60's C10 and C20 trucks. I'm sure there are lots of owners of these trucks that would be interested in a detailed description of the parts needed and the processes involved.
