Caliper bkt is torx 60 and you will need a HD 1/2 drive unit, I believe the inline for the core is off the thermo housing, not positive though.

Thanx for your response and information.

I'm not familiar with the Thermo Housing item unless you're referring to the thermostat housing, which would appear to be on the top rear (driver side) of the engine at the base of the upper radiator hose. The heater hoses connect near the left (firewall) front (passenger) side near the top of the engine.
