the first driveshaft i used was directly out of a 2.3 5speed, same length and had a 24 spline yoke like my automatic driveshaft did. the second one i bought was from a 5.0 t5, it had a 28 spline yoke that bolted straight up to my 2.3 t5. maybe someone changed the yoke on the 2.3 5speed driveshaft to a 24 spline, who knows...but it didnt work and the 5.0 one did, length wasnt the issue i knew they both the same, i just didnt have the right yoke. its all good though, runs and drives
