Original factory shocks?

strong textI have found replacing shocks on vintage cars a waste of money since todays shocks are worse then original factory ones. My 1976 XJ6 has Girling shocks…are these the factory shocks?
My 63 XKE which has no front coil springs…when the shocks went…you can tell because you feel your on a bowl of jelly. They were replaced with Kona shocks.
Are these Girling (if spelling is right) original XJ6 shocks. My Jag XJ6 had 124,000 miles on it.
What quality brand is equal to factory shocks ?? Thank you.

**I will reply to myself…yes Girling were factory shocks. Will replace with Ultra Gabriel shocks since
they are affordable from Rockauto.
