Which one and why?

U can still buy the rope seal new. Kim
I don't know for a fact. But I understand the new rope seals are not as good as the old OEM ones. The old ones have asbestos in them and the new ones don't. Like I said, that is what I heard, and don't know if that is true. I have a couple of NOS mopar seals on hand for a motor I'm building.
