between the oil Korean war era rope style seal, and the newer one? This is what L&M engines told me:
"We used our WWII/Korean rear main rope style seal, as that is all we are currently aware of.

5 years or so ago, the seal manufacturer had 500,000 2 piece lip seals in stock and all were damaged.

This came about from us investigating the source as all the seals we obtained from all the seal vendors were damaged."

There has been numerous discussions/debates on M38A1 rear main seals.
Here is a good one that I saved in my Favorites:

Thanks! That's what I needed
