Looks like we've got a way to start building full spools for the "8.4" rear diff. This is the diff in non-trd Tacomas, t-100's and Tundras. These would be a heat treated, cromo spool. Scalloped, lightening holes and all. Price would hit 200, maybe a bit more. We've got to order a bunch of these, and I dont want to order 100 and stare at 99 for 3 years, so post up you'd be seriously interested!
