A long while back, I ordered a yoke for a Chrysler 8.25 and the one they sent me did not fit. They promptly sent a replacement that did fit. They promised to send UPS to pick up the old one, but after a while, I forgot about it when the delivery driver never asked for it. So for a couple of years now it has been taking up space under a shelf somewhere.
Today I remembered that the sticker I found under the part number of the ill fitting yoke matched the later style 8.25. I had discovered that the later yoke had enough material on it to drill and add U bolts. So, I figured if I could find the funny yoke, I might work with it.
I little searching turned it up covered in spider webs. I also found Jennifer’s long lost hair dryer as well.
So I sat the yoke on a Chrysler 8.25 pinion and found that, after two years sitting in a box, it still did not fit. I double checked and sure enough the pinion for the early and late 8.25 rear is the same.
I counted the splines on both yokes and they were the same. I measured the inside diameter however and found the funny yoke to be a few thousandths smaller. That is when I noticed something I had not noticed before: it is drilled for U bolts, not tapped for straps. Cool. Now what does it fit?
It looked like a D 35 yoke so I tried it on a D 35 pinion. It mostly fit but it seemed the wrong depth.
Next, I dug around and found a D 30 pinion. Perfect fit! I did not have a D 30 seal to test the OD on but I am guessing it is a Dana 30 U bolt yoke.
So Jenny’s XJ will likely get a U bolt yoke when I install her 4.10 gears. I just have to confirm the OD.
