I would like to know where to find the Schematics/Exploded View and the brake down list of parts for a Saginaw Power Steering Gear Box (7802644) and a Power Steering Pump for a C10 Chevy Truck V8 years of 67-72. I want to re-build both of them just for the Experience, well that's not really why its because I am 65 yrs old and have a little bit of Arthritis here & there so moving the joints keeps the Arthritis at bay. Any help or directions or any video/links to these would be greatly appreciated. thanks Marvin
