Actually there are two 1/8" pipe bungs welded on the lower left corner. The second is for the "leak by" hose from the oil piston. As the piston is on the interior of the car, Chrysler added a nipple with a push on hose that returned any oil that leaked past the piston seal back to the eng, via the valve cover in 58. 57 did not have the fittings on valve cover and plumbed different. Still discounting new parts for sale. Best price on cast iron TF deluxe kits, and I pay shipping in the lower 48. If you want a list, mail me.
