Thanks for all of the helpful replies. I decided to stay OEM for right now. There is a photo of all the parts with the part number labels visible below. I also typed the part numbers below.

The total cost of the parts listed below was $370. I placed the order online and picked the parts up at my local Toyota dealer. The price was exactly the same as Camelback Toyota. The price of the steering bushings kit was $28 delivered from Amazon.

For my 2001 4WD Limited I went with the 99 tall rear coils (red/yellow). I selected the rear shock absorber listed for a 1999 4Runner SR5 4WD with 16” wheels. There are several Toyota part numbers for rear shock absorbers (probably any of them would work), but I thought it would be best to use the 80693 shock.

I may end up with some extra washers and retainers, but I wanted to make sure that my mechanic has everything that he needs. I am also getting an Energy Suspension rack and pinion bushings kit installed at the same time. My out the door price estimate to get the rear shocks, rear springs, and the steering bushings installed was $500. It was more than I thought, but I can walk from my apartment to my mechanic’s shop in 5 minutes. I’ve shopped his rates around town in the past. He is always the lowest and does quality work quickly. In addition his estimates are always on the high side. My guess is that I will end up paying less than $450.

Hopefully this post is helpful to other forum members wanting to do this same replacement.
