Need Some Yoke Education Please

My car came as a roller, so I've been chasing a lot of miscellaneous items. I ordered a new U joint strap and bolt kit for my rear (7260), which is an 8.25 out of a 74 or so Duster. I want to chase the threads on the yoke while waiting for the kit to arrive. Can anyone tell me what size the threads are on a 7260 yoke? If you really know your stuff and you have time, I'd love to soak in as much info as you have on yokes. I thought I read on the site the 8.25 and 8.75 A body rears all came with a 7260. I find it tough to imagine a 68 383 Cuda 4 speed had the same yoke on its 8.75 as a slant six with a 7.25. Could that possibly be true? Appreciate any info guys.....
