I had to di the full flow filter conversion on my 270.



I have heard of using a Chrysler one piece seal but was never able to find the details. It does involve quite a bit of machine work. Best Gasket makes the best rear main seal I have ever used. It comes with a template for trimming to make sure you get the right amount of squish on the seal.
