OK, I finally got some info from toyotapartsales. Looks like the cheaper kit is only for the sector shaft. Doesn't look like it has seals for the input side.
The complete kit has it all. That part is obvious. I needed both input and output seals and it looks like the cheaper kit won't do it.
If you only leak at the pitman arm, the cheap kit will do it.
The complete kit 04445-35080 contains all that is in sector shaft kit 04455-35050 plus much more.
OK, got the image to load. Hard to see but, the green highlighted area is the cheaper 04455-35050 kit. The blue shows complete kit 04445-35080 which is all 3 boxes.
