Tom - good information, thanks. I have been trying to guess distances from some of the pictures, but that is hard to do. At least your dimensions will get me in the ballpark.
Big Chevy - I am going to buy one, just have not got around to it yet.
Marty - yes, it would have been MUCH easier to start with a 3100 frame, but nobody was giving them away. The 3600 and 78 C10 parts were free. It is amazing how much trouble some of us will go through to make free stuff work, when we would probably be better off time and money to buy the right stuff to start with.
