Does the crankshaft guide hub on the converter vary in size or change over the years? I thought all 225 904's had a 1:55 inch guide hub on the converter. Am I wrong?

Yes early engines (crankshaft) had a smaller centering hole in them, later cranks had a larger hole.
That is why I run a stock converter in my Dart.

Howdy Richard! Good to hear from you.

So if I have a converter made, they have to know first how many splines on the input shaft and the year of the crankshaft...yes?

That sounds correct, early trans had smaller input shafts, later ones had larger input shafts. The crank could be used from a newer (say mid-70's) that would have the larger hole in the end of it and if it's from an older mid/earlier-60's will have smaller hole in the end.

I think 1967 was last year of small end crank.
