The one that uses a 3/8 extension is a restriction to the system. I use the one that uses a 1 inch socket, and drill it out to 1/2 inch. Along with all the other 1/2 in stuff Guitar Jones recommends.
Always seem to have very good oil pressure. And I run solid rollers in LA blocks.
I know I have a plate and probably the filter bolt, if ya need it.
Thanks for the offer but I had called the dealer after posting this. The plate is 53021053 and the filter bolt (Dodge calls it a connector) is 53007563-AB. It's a 1/2" internal diameter with a hex shoulder in the middle. $17 and I'm good to go.
