Thanks for the Kudos Tim!

According to what your saying, There's more than one way to skin a cat.
You can Press these inside the Spring Seat metal housing.
Which is probably the cheapest route.

Or spend big bucks,
Re-vulcanizing them at Steele Rubber or on the planet Vulcan. Spock's home planet.
Pricey

Or luck out,
and find some NOS or Used Spring Seats.
Old rubber, not good.

I like the first way the best!

Peace Out
