Ok, I asked a month or so ago whether or not the buick TR/GN regulators were the same as ours. While the factory ones have a different pressure rating, the aftermarket are interchangable. Eastern Performance, offered these trick remote adjustable regs, however they have moved and are doing business as ESP Products.
