Heater box details for link between hot/cold lever and blend door
My 1987 Trans Am GTA with AC and digital dash is missing some plastic details as seen broken off in the picture. I hope to find these original parts for connecting the lever to the box, I might buy only the small pieces or perhaps the lever too if the plastic is to brittle to come off. Because of international shipping I prefer not to ship any complete and large heater box.
All advices on where to buy will be appreciated. For instance car wreckers, people who have discarded the box for racing purposes or somebody else with a partly broken heater box where it ended up on the shelf.
Shipping to Norway, Europe. Payment via pay pal.

That piece attaches to the box and I should have a extra box here. I will look in the next day or 2 if you still need it. If you do PM me so I know to look for it

Re: Heater box details for link between hot/cold lever and blend door
Thanks for your offer. The box pictured doesn't appear to be the same as mine, could it be one without AC function? It looks like the flap door is wire operated? My box have a vacuum operated rod handling the flap door, you can see it broken off in my picture. I don't know if the plastic detail/link is the same? Can somebody please advice?

FLYNLOW92rs does have an AC heater box.
I do not believe the rod itself is replaceable. IIRC you would pretty much need to destroy the box in order to get that rod out - or to try & replace it.
When I looked at my 88 GTA AC/heater box and a regular Camaro AC heater box they appear to be the same. Your GTA simply has a bracket on the far right with an added soleniod & relay. The rod on your electric blends motor should attach to the rightmost pin on the boxes blend door rod attaching point. ( on regular cars the cable attaches on the left - as seen in FLYNLOW92rs pic. ) Your pic only shows 1 pin because yours is busted...... it should have 2 and the electric blend motor should connect to the pin on the right.
Here's a pic of the Blend door Rod in my 88 GTA.

I've got an AC box too,..... $50 + shipping. ( international shipping might be cheaper without the heater core installed due to the wieght )
Send me a PM for more info if your interested.
