I laid out the holes for the AC hoses on my Larks firewall the other night based upon the installation instructions for the 1962 Larks. However the placement of the lower hose looks like it will interfere with the cylinder head or the exhaust manifold if someone ever decides to install a V8. The lower AC hose is the vapor return and is at the same level and in line or parallel with the lower heater hose, but 5 & 3/8 inches measured from the side of the existing heater hose to the center of the vapor return hose toward the engine. I have an OHV6 in the car and I will have to use a right angle drill to access this inner hole. This is one of the reasons I am thinking there is something wrong with the instructions. Any pictures of existing installations or measurements will be most appreciated.
