Hey guys, I’m in the middle of replacing the engine in my marauder with an aviator engine. Would you guys happen to know the part numbers I need for the O-rings that go on the nipple on the backside of the water pump, as well as the O-ring for the engine dipstick tube? I thought I had the right O-rings from Fel-Pro for the coolant nipple, but they are a lot thinner than the originals. And I can’t locate a dipstick O-ring anywhere. Thank you!
