hi i'm trying to do some research for the 1968 three speed on the column 4x4 truck my step father now owns one; That we happen to find in the bushes and are trying to restore back to original. We have part of the window sticker stating that it is in fact a factory 3 speed on the tree 4x4 c10 but im curious as to how many may have been produced and any other information that may go towards the rebuild will help thanks in advance.
