The tag says the right year for your car but those 2 pieces don't fit. You don't want to stretch them. Contact NPD tell them, or maybe Rick will chime in. Or did you get them from NPD.

 

Do you have factory air or dealer add?

 

factory air

 

Is that an aftermarket heater box? I don't have the AC but all my heater box internals were metal, what you have looks plastic? If it's a reproduction box maybe it's not the same size openings?

 

Nope. It's all factory stuff. AC/Heater boxes look quite different than just a heater box in a non-AC car

 

Run down to Michael's and get some of this... 12" x 18" Thick Foam Sheet by Creatology™ | Michaels and a can of spray adhesive and make your own. My vent door seal is made from a scrap "punch out" from a vacuum cleaner seal kit I pulled from the trash.

Ah! that's a great idea! Thanks.

 

I bought both brand of A/C seal kits for my 67. I found that some of the seals in one kit worked better and some in the other. I know, what a pain.

 

It really is a PITA since I'm ready to put it back together. Oh well. What can you do? Suppose I'll make my own like Woodchuck mentioned.

 

@Woodchuck your idea worked brilliantly! Although I forgot to buy a thinner sheet for the flapper door.
