Chrysler 8.25 u joint straps

[Vandenborg1]

So i bought a donor xj for the axles awhile back and the po had taken the driveshaft out as well as the straps and bolts. I now have it in my mj and bought straps that fit. They came with bolts but they don't thread really well I'm unsure if it's due to the dirt that was packed in the holes or if they are the wrong thread pitch. I did try the bolts on the d30 yoke and they thread fine. However before I go cranking down on the bolts and pushing the dirt out I want to make sure they're the right bolts so if anyone could let me know I'd appreciate it.

If you can poke a pick in there or a small round wire brush it can help clean them out. Ideally you'd use a thread chase to clean out the bolt holes, you can make one by cutting grooves length-wise down a sacrificial bolt. Should be the same as the front though, 1/4-28, typically called 1/4" fine thread or 1/4NF.
