Hey there, i'm a newbie to Camaros. Corvettes I know. But I just bought a 69 ss 350. It is very nice but I'd like to put in a stock tach and move the fuel gauge over to the center. Now I know they sell both, but I'm not sure if I need a new harness, (full or partial). Am I geting into something real big? what might be the steps to complete this? Someone must have done this before. The former owner added an aftermarket tach which works great but.... Any and all opinions are welcome. Great site BTW.. hope to used it alot..Dan
