As I mentioned the shocks and springs are listed before or after 06/92.
I will not go near the local Dealer; BMW Calgary Crusaders
From what I hear, just the two rear OEM BOGE Shocks cost over $300 US uninstalled from the Dealer's Service Shop; going aftermarket sounds less expensive for way better product.
I also do not own any BMW or Bentley Service Manuals so I'm SOL there too.
But hey, if I knew the answers to your questions, I wouldn't be asking...
