The intake manifold for the 235 changed with the 1950 model.

1941~1949 manifolds for both the 216 and 235 accepted the Carter type W-1 carb. This link will help you identify the W-1 carbs:

For the 235, best would be either a 483s or 574s. The 684s will function equally as well, but will be significantly more expensive.

Good carburetion is fuelish hot air
The most expensive carburetor is the wrong one you attempt to modify.
