The answer to my question looks to be you take out the bypass behind the oil filter screw on fitting and then that makes the oil cooler adapter internals the exact same as a non oil cooler adapter, plug the cooler line ports with 2 3/8"npt fittings and your in .Putting it on now.Thanks for the suggestions. I hope this helps someone else.I am going to put the cooler back in service the next oil change I will use fittings like 67 chevy mechanic did on the adapter instead of the quick connects and will cut the outer crimps off my lines and remove the bad hoses, then get new high quality hydraulic hose to slide on the barbs and double clamp with hose clamps.
Proper high pressure hydraulic hose has such heavy steel braiding that it has to be crimped to seal. Normal hose clamps just aren't strong enough.
My buddy who is in the hydraulics business made me aware of this recently.
