Vent window seal difference?

My 1973 plymouth Valiant needed new vent window seals, every one that I searched said 1967-1972, I could never find any that a for later years. I ended up purchasing these and they are made by Metro. They kind of fit the same but they don't seem to create an air tight seal.

Is there a difference between 67-72 seals and later year vent windows? If so where do you find them for 1973 and up.

Hey C2ndLTpigeon,

I'm pretty sure they are the same vent window. I replaced mine with Metro Parts as well on my 68 Cuda and it might just take a little while for the new rubber to conform with your frame and glass. I helped the process along with a heat gun.

Hope this helps.

Cheers!!
