Replaced the heater unit in my sisters 66 LHD coupe yesterday. Original heater core had split and the heater box unit was in a very bad state.
All parts were supplied by Bid Al at Big Al`s Mustangs (02 9622 8289) except for new heater hose, clamps and top up coolant.
Very well packaged and presented unit
Chose the brass core
Brother in-law earnt his keep,glovebox must come out but A/C unit stays
Found original solenoid wiring loom had been very badly damaged at some stage, surprised it hadn`t let them down by now!
Reused an old backing plate and fan scroll on the new fan motor, thanks Big Al
Jobs done after a few hours, just had to bleed the system, top up the coolant and test run
