Tranny cooler lines

I made mine lines from 4 pieces of steel tubing. I put 2 compression unions under the car. Worked both ends toward the center. All except the unions is skinned with neoprene fuel hose. Unions staggered about 3 inches apart for wrench clearance. Tubing and hose from auto parts store, the unions from Lowes. You wouldn't save much if you had to buy the tubing bender though.
The reproduction preformed line install... I can't imagine slant 6 being more difficult that V8. Separate exhaust flange. Lift the radiator maybe?
