Hello

Thought I would pass this along, There is a message board dedicated to trucks like yours, with lots of people who have lots of experience with these vehicles.

http://www.67-72chevytrucks.com/ go to the message board and introduce yourself. ( you may already be a member if so great. if not please do.)

Anyway someone there can answer most any mechanical or other questions to help you with the tear down and reassembly plus any modifications you may want to make. The board has been helpful to me in my restoration of a 68 c10

Hope this helps.
