www.speed-source.net for the bushings that go on the tranny levers and
www.machv.com for the Symbrowski kit that goes on the shifter base. I am sure if you go on eBay you could find similar products for cheaper, but these are both the brands I used and the fitment and quality was top-notch. The Symbrowski kit also includes a tube that nobody else does and it also helped tighen up the shifter so i say its worth the extra money.
