The new floor-pan sat high on the chassis so I made a frame to bridge the gap between the chassis and the floor-pan which was about 5".
I also mounted the hand brake and gear stick.
BUT!!!
When all was assembled it was obvious the cab was to high.
So the 5" frame work was removed along with a very large chunk of the floor-pan.
I also had to remove some of the lower cab but this left a much more suitable looking fit.
