Can o' worms 90 degree oil filter adapter
I had a 72 318 Dart with the 90deg. adapter. It too had a (small) leak. With headers on the car, replacing all the gasket/seals on the adapter, ON A LIFT, when I was only in my early 50s, it was a PITA, but like barracudadave67 said, I got it done. Just take your time, & don't forget to use jack stands if you're working on your back. Better yet, use car ramps (back onto them, that way they'll be in front of the tires, giving you some more room) instead of using a jack, if you can.
