Just go to your local junkyard and look at the oil pumps on all the older mopars one of them should have one...(common on 225 truck too...)
Just pull the oil filter and check for a 3" long or so pipe that has the end cut at a 45 degree angle...I forget the wrench size (3/4" or 7/8") will be needed to unhook it from the base of the filter "bowl"...

good hunting

The wix filter is a 51515. Same as the tall Motocraft design. Has the check valve built in to stop drainbach. I use one even though I have the tall filter adaptor. My slant with, the 390 holley won't actually start ( When cold) unless I jab the throttle once or twice....so I crank the engine over until I see the oil press needle move. Then I pump it once and she fires. No more dry starts. About a year ago I installed a starter button on my Ramcharger for the same reason.IT works through a relay so it can't be ingaged when the engine is running.
