I suppose that the sheet metal pan at the lower passenger side of the engine compartment could be modified to allow for the exhaust pipe to be further back...but I wonder of there would be other conflicts.
I would assume that there have been plenty of 235s dropped into these earlier frames and perhaps someone here on the forum would be able to let me know if they are aware of potential pitfalls.
One complicating factor might be that the cab is a 1940, but the frame appears to be 1941-'46.
I have attached a photo of the left side of the engine from when I received the project showing the proximity of the steering box to the current location of the exhaust.
