Okay I know those cats are messing with you but here's the slow scoop on that. they're trying to say is the shaft that you want you know doesn't go all the way through the transmission it stopped short at the front and then butts into the one that actually does come out the front. I believe what they were good in that is theirs Factory clarence's between the two that have to be pretty correct. So getting them together gets allI the tolerance is correct automatically more or less without fighting it.
All 727 are strong Transmissions LOL if you want my personal opinion if that transmission ran so good I would try and sell it and just get the correct one it's just so much less hassle. Even to get the correct one and put $120 rebuild kit in it.
