So, I emailed Klune to see if they could provide any updated information, and here is what I got back from Julie Davidson:
"From what little info I have on the Explore, I don't know that the Klune will bolt to your tranny or t-case. The 2 basic requirments are a 6 bolt circular pattern and spline count. for Goliath we would need either 23, 27, 29, 31 or 32. 31 is a typical Ford spline. For the t-case, we can offer the same output shafts, plus 6 and 10 splines. If you have teh 25 spline Mazda tranny, it won't work. In many cases, Advance Adapters makes kits to bolt various transmissions to Jeep t-cases, such as a Dana 300 or NP231. If they do have a kit, there are possibilities.
Wish I could be of more help. If there's anything else I can do, let me know.
Thank you for inquiring.

Unfortunately, I don't know the 5R55E bolt pattern enough to know if it's a 6 bolt circular pattern. Hopefully someone else does?
Likewise, while I know the axle shafts have a 31 spline count, I don't know if that's also true of the Tranny and T-Case?
