Finally lifted! The Rusty's 3/4" spacers worked perfectly. In fact, it looks to me like they yielded more than 1" of lift overall, but I didn't take before and after measurement. When I was finished installing the front lift, I started to wonder how my 2" terraflex rear spacers would work. So in they went, and boy am I impressed with the results. Now having said that, I don't know if this would work with a non-CRD KJ, but I don't see why not.
I bought the 2" terraflex budget boost before I learned about the problems with OTT lifts, so I don't know whether or not the rear 2" spacer is for sale separately, but I would say it's around $75 or so. The installation went smoothly. I spent about 5 hours on the front (it would have been less, but I spent about 1.5 hours traveling to the base auto skills center to use their very nice spring compressor to install the spacers--a really good spring compressor is a must as it took alot of force to compress those CRD springs with the spacers). I spent less than 2 hours on the rear, and for a homemade spring compressor, I used a small ratcheting cargo strap--worked great.
Regarding my original question (which is now a moot point), I found a great budget boost that won’t damage anything. Here's some before and after shots
