KB,
First welcome to the pages.
As to the VIN, look in the TECH TIPS and then IDENTIFYING YOUR TRUCK section. There are a few vin busting resources.
As far as power steering go to the 60-66 forum and look for the thread (2ish weeks ago, 12/31/14) titled 60-66 resources. Linked in many of my saved bookmarks. Additionally WOOGEROO restarted his thread linking in his web page with many resource materials. The power steering parts should be in there somewhere. Finally, Tony, from 456 chevy trucks fabricates the brackets and has the whole package (I believe).
Give those a look and then come back to us if more specifics are required.
