UPDATE: I got my endlinks installed (very nice difference). I followed SilverBullet'* instructions and all went well.
I tried not cutting the spacer for the fronts, but couldn't get it to work. (BTW- I'm 380lbs and I literally hung from the front sway bar while my buddy tried starting the top nut. No luck. :P ) Ended up cutting a 1/4" off and all is well. Rears went in no problem.
As for the sway bushings, I did some measurements and I think the universal numbers listed previsously will work. I ordered 9.5171 for the front and 9.5124 for the rear along with some prelube.
For the fronts, the new bracket should work. As for the rears, the stock bracket will have to be used since the bracket is in the form of a D. It only has one bolt to secure it to the frame. (It'* kind of like my GTP.)
I'll target to get these installed next week sometime. I'll keep everyone posted.
