Prothane's Poly manual rack mounts, part #18-702-BL, which are compatible with AW11 MR2s and AE86 Corollas also work in Al25 and Al21 Tercels. You can get them for less than $10, where as the factory Toyota replacements are over $35 at cost. They fit nice and tight, no play or binding. I won't have a chance to drive it for a bit but it looks very promising.

Installation is pretty straight forward after getting the rack out. Clean everything Very well. I recommend lubing the bushings inside and out with Prothane's Poly-grease. It'll keep the Poly bushings from chirping when they get covered in mud and gunk down the line. Wipe off excess after install and clean with rubbing alcohol. That stuff is sticky!
