Michael.....the transmission lines should be routed between the motor mount and the engine. The clamp that you have attached to the rear of the head is to hold the transmission dipstick in place. The tube for the heater return (lower heater core nipple) is held in place with that clamp on the tube. The clamp is screwed to a hole on the crossmember just below the grease fitting for the upper control arm shaft. The upper heater hose runs from the intake manifold nipple to the upper heater core nipple. The upper hose was also supported by a slightly twisted clamp that attaches to the rear generator bracket. I see that you have an alternator, so the generator bracket is probably missing. The purpose of that clamp was only to hold the rubber hose off the valve cover, so it's no big deal. Hope this helps.....John
P.S. keep up the good body work!
