I recently did mine, and it only took just over a day (I went slow). And I hadn't touched a steering rack in my life. I also got mine welded @ Vorshlag for $20 and I highly recommend that.
Also, I couldn't find a idler either (they're $$$), so I just gutted the PS pump and it works just fine. Just pull the vanes out and plug the holes. Took me all of 10 min after I had the pump out.
You'll love the depower, its the best improvement/$ mod I've done to any car.
