Default 9" experts: Yoke length question

I'm building a 9" to install in my '95 Z28 with a long-tail TH350. I plan on using the stock aluminum driveshaft. I purchased 2 yokes for it. According to the guy I bought them from, only 2 yoke lengths were ever offered for the 9" (by Ford, at least). However, when I measure it, it looks like one is 1/2" too long, and the other is 1/2" too short. Anyone have any idea which is the correct one to use with the stock driveshaft?

Thanks,
Mike

I appreciate the input, Scott. I have 2 Ford yokes here. How do I know which is the right one?

The short one (M-4851-A) should be about 3" tall overall and the tall one is about 4" overall. I can measure the M/4851-A yoke if you need exact measurements.

This gets more confusing by the minute. . . my short one is 4" overall and my tall one is 5" overall. To further confuse things, the tall one is narrower than the short one, though they both are machined for 1.125" u-joint bearings.
