s10 T5 yoke question...

[erock805]

So just about have my step dads up and rolling. Just need a drive shaft. I put in a small block and a s10 5 spd. I am on the hunt for the right one. It looks even the s10 one will fit. I pulled one from a short bed square, automatic, and it seemed that the yoke was different. Looked like a smaller spline and looked like one spline was missing (not shaved off but factory).

I have a 26 spline coming out of the trans...are there a bunch of different options with s10 yokes? I am pretty sure that the s10 came out of a square. Want to drive this thing around the block...
