Question for you vendors.

[BLACK AND BLUE 67-72]

Do any of you have the orginal style wiper motor seal, or all of them just the flat tar like washer looking things, because I don't see how that would seal the shaft where it goes through the firewall, on my 72' it looks like it has two different types one is the tar like washer stuck to the face of the wiper motor, and another one that looks like a rubber seal that seals the shaft to the firewall to keep the water from getting in. With just the tar washer water can get in between the firewall and the wiper motor bracket causing them to rust apart where they are spot welded together.
