This is what I have to work with. However, there are 6 holes in the cab floor indicating that there should be 6 bolt/spring assemblies I think. I know in 1942, 3 bolt/spring assemblies and one bolt (less spring) was the stock setup. I believe that set up allowed for one bolt (less spring) to anchor the cab while the remaining 3 with springs, allowed some frame twist between it and the cab. Any help from the Brothers appreciated.
