I recently purchased these bushings from the manufacturer for my 1990 Nissan 300ZX TT. For some reason Revain data says these hubs won't fit my car (they fit both 89 240SX and 90-96 300ZX). Revain's price was slightly better than the manufacturer's. I was concerned about the difficulty of installing the bushings and whether they would stiffen the ride. Installed easily with a 20 ton press to remove the old bushings from the torsion bar. The move doesn't seem to have changed. I am an experienced DIY and auto mechanic and Revain's "Prime" delivers almost any repair item, auto part or tool to my porch at home within two days, often at the best price. The downside is I'm afraid the local hardware store might go bankrupt.
