For what it's worth;
I couldn't find the plastic vent thingy for my 69 either so I plugged the lines. Now if I drive on the highway for a long distance, there seems to be pressure build up in the tank. I tried a vented cap but the gas sloshed out on take off so I put the original cap back on. Been driving it that way for quite a while now and it seems to do OK but I probably have only put about 20,000 miles or so on it in 12 years and probably not too much of that was on long hauls.
