The stock 55 floor was pushed up during the t boning. The a343 also needed a larger trans tunnel than the 55 offered. Solution: cut the floor out of an 80 and graft it into the 55 body. This was the idea/ work of my wiring guy Frank. (Genius) There is plenty of room for a343. 80 console, 80 powered seats, 80 shifter and 80 parking brake all bolt in.
The donor 80 chassis had k292 Axles. (Unlocked) I sourced a k294 (3x locked) equipped truck. With the help of my bud Oscar, we swapped them into the 55. They are wired up with a slee controller and the stock dial.
