Can someone explain if the original O-Rings are round or have a square shoulder. The ones I got are flat and thinner than the round ones that are in there now. The flat ones are made in USA by Mahle. I got them from Rock Auto but Advance has the same ones. They only give you 6 for some reason. I reused the ones that were in there. They don't leak so I did not want to cause a leak.
