Hello all, I have been lurking the forums until my truck got shipped in yesterday....To the right of the original gauge cluster, there were a 3 gauge set added. In the original cluster the only thing that appears to work is the air pressure gauge. I want to trouble shoot them, but am looking for a schematic. Also looking for parts sources, right now, I need the exhaust manifold gaskets to cylinder head on the passenger side and a rebuild kit fo the clutch master cylinder. 1963 Ford C800 534ci 5spd trans towtruck......getting ready to be a dump truck

TIA, Chad from Charleston, SC
