I got mine from Hamilton Marine, a local boat supply store. They are also online at
http://www.hamiltonmarine.com and they are real friendly folks. They also sell hammerite paint, which I highly recommend.
I bought my stud extensions locally, at a large bolt supply store. They are metric and can be found if you look hard enough, if not, the store may have to order them for you. I then used bolts on the bottom part. I thought about drilling out the studs and replacing them with bolts, but it'd be a PITA to get at them all. I used grade 5 bolts (8.8 metric), I think, as the studs aren't grade 8, and neither are the extensions. The extensions are about 2" long (maybe 1.5"), so they get some good bite, and Loctite is a good idea, but not the high strength kind that requires heat to loosen. My body tub has taken quite a beating in the last few weeks, so much that I broke one of the front cast steel rollers and bent the 1/2" grade 8 bolt, in addition to rolling it into a Toyota, and jumping it while rally racing down a road. Most of this was with a passenger and about 300 lbs in tools in the rear bed, which I found lets the Calmini suspension flex well, right <font color=blue>mxnhid</font color=blue>? Prior to installing the rollers, the fangs used to hit all the time as well and the 1/4" steel on the front is kinda of dented a little. The body and lift has not shifted, loosened, cracked, or shown any signs of abnormalities at all.
For the 2", I had to realign the fuel filler hose, do the steering shaft lenghtening, and I did have a problem with the 4WD shifter. I notched out the front of the tunnel so it would stay in 4L, and then rotated the boot 90 degrees so the boot would not pop it back out of gear. Never did anything to the tranny shifter. I also do not have anything under the mounts that just rested on the frame.
Chains aren't a bad idea, but unless you plan on rolling it over and over, I doubt they'll be needed.
It took me a long time to find all the components, set them up, and install them. If I had to do it all over again, I'd probably just shell out the extra $50 and buy a ready made kit, it'd save a lot of time and frustration. I'm also venturing into the unknown with this, if it snapped, broke, or messed up something, no problem for me as it's not my daily driver, just a rig I wheel, so no problem if it's down.
