Heater Plenum 1965-1968 is rated 4.6429 out of 5 by 14.
Rated 5 out of 5 by from Small, seemingly insignificant part -- NOT! I was desperate to restore heat to my beloved '66 convertible, with cooler days coming. I ordered the heater core and set about getting the hot air flowing. Then, I saw the existing heater plenum - cardboard! It was ratty, ripped, and almost non-functional. If you are restoring your heating system, BUY THIS. It's a cinch to install (much easier while you have the heater box out...I found out the hard way) and the flaps that control defrost and heat function much better within the rigid ABS frame. DO IT!

Rated 5 out of 5 by from Heater Plenum Review Purchased after noticing my original cardboard unit was in bad shape. Wish I had noticed before heater core replacement. I have not yet installed but would likely have been easier if done during core replacement.

Rated 5 out of 5 by from Better Than Original The original was that flocked paperboard and was beat all to pieces. I bought this as a replacement and it works great with my rebuilt heater. Highly recommend!

Rated 5 out of 5 by from excellent fit My heater plenum was broke where cable was located. New one is better material (plastic) unlike the cardboard type of material original is made from.

Rated 5 out of 5 by from Good quality product! This was definitely a step up from the original plenum that was in the car...and falling apart. Fairly easy to install and a good solid replacement.
