My '35 1.5T has a '48 216. I think the PO wanted things to look more original than in would than the more modern 235. If you do go to the 235, make certain you get a later shell bearing version so you get the advantage of the newer tech. The older babbit metal ones just don't hold up as well, a consideration only if you intend to drive much. 216s on the other hand, are dirt cheap, compared to a 235. My conversion uses a '46 bell housing, so the bolt pattern matches, and the clutch mounting (it's on the housing) remains the same. If you get the right bell housing, it should be easy regardless if you go 216 or 235.
