it is mounted to the bottom of the heater box, the same side were the lever is where the cable attached.
I read a post where a member was looking for the same part and could not find it - then he said nevermind found it - I messaged him with no response - the post was over 5 years old.
I gotta tell ya guys I can't find that same style part design anywhere is the number correct ? Could GM have changed it mid year or so of 69' build ?
If I see something I'll send it your way.
I have a late build 69 (Oct 24, 69) with no A/C and if that is the actuator on the drivers side behind the removable side panel and above the radio, mine has the flat pancake actuator in caskiguy's posts.

Had the same issue with mine some years ago and tried sourcing that same part - ended up rebuilding my original (difficult).
Unfortunately that part was never sold by Chevrolet separate from the heater distribution box.
The heater distribution box is supposedly the same 68-75.
There's a "Corvette Original Heater Core Box Assembly" on ebay now you might want to look at.
