I just did this on my 2001. I got 2" of lift. I made the BPV out of some flat stock, and for the brake line I just bent the bracket up, then flipped the e-brake cable on the gas tank so it will not rub on the rubber.
It took a while to find the dimentions I needed, but PaulW was kind enough to run to his truck with a measuring tape. Here are my findings:
Here are the dimentions as follows, 1 being the very first spring (with eyelets), 6 being the overload. The first number is the ammount in the front, the second is the ammount on the rear. The dimensions are from the end of the leaf above, to the end of the leaf...
1 (Eyelets)
2
3
4: 6.5"/8"
5: 3.5"/3.25"
6: (Overload)
I decided to drill the holes on the end for the stock pads. I also cut the corners, then grinded it round and threw a slight bevel on the edge. No squeaking, and looks very stock. However, if you decide to drill the holes, either have a Drill Dr. that you have experience with, or you can sharpen bits really well, because I tell you, you will go through bit after bit trying to drill a hole. I had to go in 3 steps, and each bit was only good for one hole. That was using lube, and a drill press with the correct speed. Took a LONGGGGGGG time, but IMHO, it's worth it. Do it once, do it right!
The shocks I used are Bilstien 5150's, model number BF5-A195-H1. A very nice ride.
Now, the last truck I had, had a Pro-Comp AAL, and then I went to a Alcan AAL, both available through Doug from
www.ToyTechLifts.com. I tow my boat, haul my dirtbike, but still wanted to wheel and not bang my head on the headliner. The Alcan by far did the best ride, and it held wieght good, it also flexed pretty damn well!

So far, I have only been able to tow the boat. It is very comparable, it actually holds the wieght a bit better, and the ride is a tad stiffer, but it's perfect:

Note that I do have the wieght of the sliders. Each wiegh about 75 pounds (guestimating). My leaf springs were also pretty worn out form the camper shell the owner had on before.
The donor leaf pack was from a 98 (I believe) Tacoma, 4cyl 4x4. It had a Pro Comp AAL, so it may have been slightly sagged. The only info I have for doing this is, keep the driver side pack with the driver side, and the pass side pack with the pass side. I would imagine it would probably affect the side to side lift.
I also sprayed the whole leaf pack at the same time with Rust-oleum High Performance Enamel. It's really tough paint, and the flat black came out great.
Overall, I would do it again. Maybe we can start something where members post thier numbers and the ammount of lift, and any extra wieght on thier rig?
Hopefully this helps out anyone looking for about 2" of lift in the rear.
