I meant what the sm465 came out of??? I just got back from what i thought was a deal. I got a 32 spline long input np205 and, what i thought, a matching 465 to go with it. when i got home i noticed the missing notch on the adapter. I have a pic of the th400 and the sm465 adapters. The sm465 output shaft is 32 spline male and the np205 input shaft is a matching 32spline female. The second thing i noticed was the output shaft on the sm465 is about 1/2" too long and will have to be trimmed. I may also have issues with getting the np205 levers, but it seems like it would be a bullet proof setup. anyone have any pros/cons??? here's the rest of the pics. ARQ.
