I finished the install on the L side using the original U bolts (cleaned threads) and then went back to the R side and loosened the U bolts. A very slight whack with a hammer and it dropped into place. Yay!! Got everything tightened down and back on its wheels.
I took measurements from the floor to the wheel arch directly over the axle. With the 110 lb. springs I only gained an inch. I won't have time to see if it still looks low in the rear until I take it out tomorrow afternoon, but I expected more of an increase. Granted, that's at the axle; I should also have measured at the rear bumper where the increase should be greater.
Lessons learned: a) bypass the CJ Pony U bolts, b) the locator pins you'll get probably won't be the same height as the originals, so check before install, c) if one side won't settle go ahead and do the other side and that may solve the problem on the first, and d) this is a job that will likely spread over two (or more) days. It may be the infamous eye bolts or the locator pins, but this isn't the piece of cake it seems like it should be.
Thanks for the help, folks. VERY appreciated! Nice that the wisdom of more experienced owners is available.
Ain't the internet grand?
