I paid less than $600 each for both of the 8.8s I have installed. One in Central California about a year ago(96 explorer, 3.73 and Trac Lock $575). The other about 2 months ago in reno, Nv. (95,3.73,T/L,$475). In Ca. I called all of the Junk Yards within a couple hunrded miles twice a week,(I made a list of all the yards,Ph #,contact name)taped the list to my desk, and called EVERY Mon. and Thur. morning. The first month I probably missed 5 of them because they wouldnt call me back. I finally found one at the end of the 2nd month when they were getting tired of me calling. Here in Reno I just got lucky and mentioned that I needed one for my YJ to a mechanic that I met at a local 4WD shop. As far as I know only the 95s and up have the discs, but I have heard people say that they were on some 94s??
