Dragsix is correct. Both the carb and vacuum advance on the distributor have 1/8” male pipe thread on on end and a 3/16” inverted flare fittings on the other. I used CuNi (copper nickel) brake line to plumb mine. It bends easy and flares easy. You will need a flaring kit to install a double flare on each end of the tubing. You can buy a flaring kit, tubing and the fittings at your local auto parts store on on line.
