I am running the PORC on my XJ and the AA on my wife's TJ. No difference in quality, performance, or install.
There are several guys locally that can help you install it. It's too difficult.
As for driveshafts, I used a place in Irvine, but that's real close to you. There is a place in Fullerton, Cal knows them rally well. I can't remember ther name though.
I am running a front driveshaft out of an late 80's model. The lenght was perfect. Had to have it balanced and new u-joints, less than $100! (The driveline shop in Irvine) I had to have complete shafts made for the TJ, now that was considerably more.
So, take your measurements for your driveshaft, then see what your existing front DS measures. If it's real close, then head to the boneyard and pick-up a couple of fronts and have them balanced... save $$$$
Good Luck!
