Wiper pivot to cowl seal,

Thank you!

Many thanks , A lot of these mustang parts places list the rubber as 64 through 67. The vendor I was dealing with said they don't make the leather seal anymore and that the rubber was a better seal. I knew I had seen the leather seal on other websites. Thanks again.
 

Glazier Nolan still lists the leather ones.

And the seal is not intended to deal with water, so rubber would perhaps be better- On a boat.

and why 64-67? Was 68 some sort of unwanted stepchild?
