Does anyone know if the t50 from a 2t corolla (20 spline) is bigger or smaller than the t50 from a 3t corrola (22 spline)??

I am not a member of the toyota clubs and i havent been able to find this specific information.

I have a look at a t50 conversion in Bens coupe a couple weeks ago and it fits differently than mine seems to, and I am under the impression that his is a 2t (20 spline) t50 box.

When i am trying to line up my motor and box, my box seems to sit further back by about 4" and it sits with the front of the motor tilted up.

Does the coupe have a differnt trans tunnel than the sedan?

Any info??
