I have an 07 Heritage Softail with the 96B engine and am planning to install an oil cooler. While I was looking to see about the adapter needed on twin cams engines to hook up the oil lines I noticed what looked like 2 plugs on my stock oil filter mount. I have never seen them on any other twin cam I have looked at so I am wondering if that is what they are there for. Does any one know if they are there for hooking up the oil lines on this model or will I need the regular adapter that is made for the twin cam engines. Any info on this will be appreciated.
