The trans will bolt up but convertors are different.I think you can use the late convertor on the poly but not the poly on the later crank.The difference is the register diamiater on the crank.We put a LA in the 66 Charger after the poly locked up.One bolt wont line up IIRC but it works.You can not swap convertors from late to new either.I believe 66 was the last year for different splines on the convertor.Rocky

early converter snout is smaller than the later, so you can't swap late to early, but you can have a converter made to fit the later trans and the early crank. Years ago I got a quote from a local trans shop that was reasonable and they knew what I was talking about, so call around.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

Most any converter company will make a small pilot converter.
Edge or Continental used to do them for less than $200.

When you mate a post '67 motor to a pre '68 trans you can get a spacer ring for the crank register that will let it accept the small converter pilot.

The converter hub diameter difference only relates to the 904, all 727 converter hubs are the same diameter.
All '62-later poly cranks had the large register, only the early /6 and 273 had the small register.
The only problem encountered when mating a later 727 to a poly is the bellhousing bolt pattern, there is one bolt hole that won't align.
