you sure Steve?? I just did a couple swap for guys and the angled fitting in these trannies were a 2 piece design that used an "O" ring and locknut. Looked like a straight fine thread.

They are 1/8" STRAIGHT pipe. NOT NPT.....You can get then from http://www.bulkparts.com or from your local parts store that carries Weatherhead brass fittings. They might have to order them for you. This is the fitting.....

They ARE 1/8 NPT! I only have about 20 or 30 C-4's laying around and every last one of them has 1/8 NPT holes threaded in them for the cooler lines. Early ones had a register machined for an o ring where the fitting seats also.  ------------------

Thanx,Alex. I have since seen the 2 types that you are referring to. Also I am changing the cooler on the Comet. What type and size do you use? Thanx, Joe------------------
