73 CJ5 4.0 head on a 258, HEI, Holley Projection w/ 4.56, Detroit lockers Narrowed D44 front and full float D44 rear T14 w/ D20 4 wheel discs, 38.5 Boggers
As far as splines, the output splines are different but you say you have a Dana 20 already on the T-15 you want to toss in.

And although the input shaft looks like it may be slightly different on the pilot bushing tip diameter, this should be a fairly easy swal I'd wager.

T-15 is very slightly larger (longer) by by ?/16th's so not much if any drive shaft mods?

Here's where I am reading from on them both.

But to your main question, "I" have never done it... Though it looks as if the T-15 was available as a stock option behind the AMC 258 i6 / 4.2l ...
