So I did the first of the steps to remove the heatercore.
unbolted the 2 nuts in the engine bay.
unbolted the 1 bolt under the heater box. Bagged and tagged the hardware in Ziplocs and added it to the parts list excel file.
lifted off the defroster vent trim to expose the 3 top bolts.
released the hazard and defrost switches from the bezel
released the headlight and foglight switches.
lifted the steering column trim
I am disconnecting these because the speedo cable was tight last time I was in there and only let the cluster move inches.
not bad for a few moments in the garage.
