I wanted HD Bilsteins on my 300D, but other than perhaps the dealer (I check with dealers last, because no one offers less for more money)., no one locally here in Miami had any Bilsteins, just Boge comfort shocks.
I got mine from Rusty. I wrote his address and phone down in a previous message about this that you can find, and all four shocks cost about $400 delivered. Then I got the upper yellow plastic dohickies that go on the front shocks and the bellows locally. I was unaware that I would need them until I took them off.
The hardest part for me was compressing the rear shocks and getting them into their proper hole.
