Gray used to work for Keisler and got out before that ship sunk. He is a pioneer of the Tremec installs in musclecars and is a Mopar guy.
He started his own company and supplied the hydralic kits to many of the Tremec dealers like American Powertrain until they copied his kits and started having others do it or making the kits themselves. He partnered with Eastside Motorsports
Shop - EastSide Motorsports and has been with them for the past couple of years so if you order through his website Eastside fills the order. He is a Mopar guy so he gets my business.
I have used Eastside Motorsports as well on a T56 install and they had outstanding customer service. I was having an issue with my pilot bushing size and they bent over backwards mailing me a replacement overnight. They didn't have it in stock so the bought it from a competitor on their dime and sent it to me just to keep me making forward progress on my install.
That is the best a company can do so I vouch for them 100%.
