There were two band adjustment tools as I recall, An inner band adjusting tool which was pretty much a distance guage, and the external band adjusting tool which was pretty much a rotation counter. I believe that the instructions called for setting the engine idle, turning the band adjuster to tighten until the engine dropped a certain number of RPMs and then turning them back a set number according to the counter. There was also another tool used that screwed in and adjustment was made until the tool collar just started to spin. I have most of the tools but as they seem to have quit showing up for sale, I am hesitant to loan them out. I think someone gave Bill Hanlon http://talk.classicparts.com/member.php?u=2120 as being willing to rent his out but requires a deposit before he will ship them. http://chevy.oldcarmanualproject.com/booklets/5430smindex.html
