ended up spending almost 4 hours trying to get the rear d-shaft in. first off, the disc didn't have the flange pattern i needed. this isn't as easy as just re-drilling, since sky's disc is threaded so you don't have to worry about the nuts on the backside. well, i ended up welding a 4 nuts to the back side, since i didn't have my tap set with me (luckily i did have a 13/32" drill bit with me). trying to get the d-shaft, flange and disc lined up is a hopeless endeavor... so i tacked the disc to the flange. even with the disc tacked to the flange, it's still a bitch to get the d-shaft mounted, once enverything's in there, its tight and pretty tough to get wrenches in the right spots.
if anybody else decides to run the kit, do your self a favor and tack weld the disc to the flange...
one nice thing about it is that you can use the e-brake to hold the flange as you loosen the flange nut (about 110-130 ft/lbs).
oh, and it works pretty damn well holding the rig, too!
at least my junk is one step closer to inspection!
