Easiest way is check the PK number stamping. Its on the pan rail lip on the drivers side right under where the oil cooler lines and the shifter/kickdown mechaninsm is located. Numbers are only a 1/4" high, just above the pan itself. Let us know what the number is (7 digits) or google it and you'll have your ID. Now, of course, if someone remanufactured that transmission, it going to be a little more difficult. HTH, Lefty71

If it's been apart it could have been upgraded. Only way to know is get it apart.

66 was the first year on the 727 , mechanical shift linkage as well . but the 71 to 78 has better input shaft and bushing length to the output shaft .

No way to tell for sure without removing the transmission, but if it has a smaller than stock Hi-Stall converter, it likely is not a 19-Spline input.
Thanks gentlemen. I'll get underneath it tomorrow and check for the 7 digits. I need to throw a bit of a converter in the car and would hate to spend the cash on a custom 19 spline one and find out it doesn't fit.

Agreed. No one wants custom speed parts that dont quite fit the bill. But keep in mind that you can make it work either way, meaning if you want, just buy a late converter if you choose, pull your trans, grab a late model core and make it an early/late hybrid. It would not cost that much.

Two ways to convert to 24 spline. Either using '67-70 pump stator support and narrow band drum, or '71-up pump stator support and wide band drum. You would think that just the input shaft needs to be changed, but the 24 spline input shaft is slightly larger in diameter where it seals in the pump stator support housing.
