T85 transmission to t10 bellhousing mount differences

[A440cuda1]

So I am in the process of swapping out a broken t85 to an early T10 behind a '49 Lincoln 337. I was told by a number of people that they share the same transmission to bellhousing mount pattern. It became pretty obvious very quickly that that information was incorrect. Did lincoln use a special version of the T85? My T10 is from an early Falcon.
