Is this wrong info?? Never seen the tan ones before this is why I ask. They’ve always been dark. The service manual also shows them dark.


I still have original gaskets in original Chrysler packaging from 1972,packaged in sets of thee including air horn gaskets,never opened,same as picture I posted.


Did a little more research. I think the tan ones may have been for the 440 version while the darker thinner version was for the 340s.
