Danimal - I don't post much because other projects seem to keep me away from my 66 GMC 5500, but I did get this far. My master to hydrovac setup is different, with a solid line to a short hose that gives some flex between cab and frame, but I couldn't find a stock replacement hose and had to have one made. Take the hose to almost any parts store and they can either make one or tell you where to get this done. It could be expensive, so you might call around for prices, and modern hoses seem to have smaller inside diameters - but my truck still stops.
