I know this is an older post and you've probably parted out the car already but someone else on this board shared the toyodiy.com site. It's excellent. You plug in your car and you'll get four assemblies with all the parts included. I have to dispose of my 92 LS 400. Too many things wrong with it (cat and possible egr pipe, struts, brakes, etc). I was considering working on it myself with a mechanic friend of mine who was interested in teaching, but it's just too much of a project for a first attempt (I need to start with a more basic car). It's a shame because it's low miles at 92000, no accidents, and garage stored.
Anyway, hope your effort was successful.
