- 1969 Riviera
I just bought a 69 Riviera that has the wrong carburator on it and the vacuum hoses going to the ported vacuum switch are messed up. I can't find a engine vacuum hose diagram on Google. Can someone help me out. I'd also like to buy the correct color stripped hoses for the engine and hideaway headlights. I may have to get them for a different vehicle. I found a great hose diagram for the headlights on this forum but not for the engine. Thanks to anyone that can help.
