i have still yet to order the fittings,vent and the cap. really in no hurry to get it in will pry do it this winter and tub the car at the same time. i was just looking for something to weld to try out the welder, on the other note i still have to cut a hole in the top for the cap i figured i could just put my hand through the hole before i put the cap on to put the bulkheads in. then use a shop vac to get all the shavings out.
