These high quality seals fit the heater in my 68 Standard perfectly. They are just the right thickness and just a little trimming was required.

grab a beer, turn some music on, set up the folding table and sit down with it. Every single piece of foam in the kit has a place and its easy to do once you get the old box out and apart. not only does it insulate to a degree, and seal, it quiets down the blower motor also by adding / replacing foam and sound absorption pieces

Everything you need to seal up your heater box. Highly recommended if you have your box out for a heater core. Very nice foam which fits quite well. I did trim a couple sections to ensure they fit well and sealed the desired area. Make sure you have trim adhesive on hand to glue the new stuff on

Good kit. The instruction diagram was a little hard to tell (small) where everything went, had some extra seals. But i feel the overall kit worked well.
