Just rec'd new heater hoses and clamps for my '74 tr6. When I purchased this car last year the previous owner handed me a box full of heater parts....fan, heater core or matrix, various hoses, clamps, etc. I have since refinished the heater box, double checked the heater core to ensure no leaks, cleaned and refinished the fan/motor. My problem is I can not figure out where the 2 hoses, one each side, that go in the foot wells which are attached to difusers mounted on a metal bracket. There is a 'Y' shaped fitting, supply hose from heater to the 'Y', one hose to dash heater difuser from 'Y', and the other hose mentioned above gets mounted where in the foot well?
