I recently did a heater core on my 72 cutlass s and found that the dash insulation and hoses or duct for my defrost and heater vents were in need of replacement!Where can i find this part and what would it be called?


Thanks in advance

 

I have heard that the round ductwork can be still had at some of the local parts places. Napa comes to mind......
The bigger diameter stuff may be subbed with like diameter air cleaner intake hose.
You would just need to shop around a bit.

I have not heard of a source for the rectangular stuff, other than to take the right diameter round duct and reshape it if possible - a pure pain.

the insulation can be replaced with 3/8" Dynaliner - it is like self-stick foam. Other brands would work, too

BTW, welcome aboard!

 

I've found the round ducts at NAPA as well. I think Car Quest might also carry it. I've never been able to find it at O'Reillys (my favorite place in town), Advanced Auto Parts, or Auto Zone.
