sqdeb@yahoo.com. Ask them for an Isuzu yoke with 10 (or maybe 11?) splines*. They shouldn't need any measurements. Spline count is the only thing that matters -- diameter will be right. I think this was the same spline count used on 1.8L and 1.9L applications.
As for whether it's 10 or 11, every yoke I've seen had one double-wide groove, so you'd see 10 actual splines in the yoke, but the output shaft had 11 splines. Same thing for 17-spline and 27-spline transmissions -- their yokes had one less spline.
