Once a person knows a part number, are there technical details about the part available, such as measurements or technical drawings?

The reason I'm asking is because on this other thread we are interested in finding the difference between manual and power brakes master cylinder for a 71-72 C-10 pickup (not Longhorn, not C-20, C-30 etc.), such as what is the bore size. http://67-72chevytrucks.com/vboard/s...d.php?t=807819

Those are the charts the brake engineer created in order to release the parts for production and service. They go back to 1969 and were hand written at that point. To my knowledge this is the only remaining copy.

I found out about it during my short tenure as a brake development engineer for truck. I asked if I could borrow it and it somehow never got returned before we all retired.

I thought about having the GM Heritage Center scan it and make copies but I still refer to it on almost a daily basis.

I have the charts for those 71-72 models but am at the races this weekend. I'll check early next week after I settle back in. (You may have to remind me!)
