The spot weld drill is shaped like a wood drill bit it cuts on the outer edge and a small point in the middle aligns it, i replace a wing and front panel on my old MK2 you can always drill the hole completly out and fill with weld if you'r good enough with the welder, you'll probally need to remove the door aswell to get to the welds this can be a bitch as the door pins wear and are bastards to get out, you'll need someone to hold the door and take the weight of the hinge while you batter the pin out.
