Hi Everyone, I was at the Charlotte show last weekend planning on buying a repo proportioning valve. I went to one camaro vender and he said he had so much trouble with them he was waiting for new ones to come out. I went to another vender and he talked like he hadn't heard of anyone having trouble with them leaking. Has anyone used the repo ones? Any help would be appreciated. I know they are really metering valves but that isn't what they are listed as in the books. I have a 70 model one if anyone needs one let me know. Thanks
