I am in the process of removing the dash on my 1930 726 and I can attest to the fact the the knobs on the choke and spark pulls are firmly attached. Fortunately I was able to unscrew them from the firewall. Any clues on removing the line connected to the back of the water temperature gauge? I have just about everything else pulled apart and it looks like there are three large screws on the inside the the dash on both sides holding it to the body. Anyone have any tips on this? Steve
