A few weeks ago I decided I could not take how horrible my car was riding over bumps it felt like the car was going to fall apart. I pulled the left front strut off and pull the insert out and it was completely dead . It was an old non gas KYB. My problem is I ordered a Bilstein off Ebay that listed the 73 Bavaria as a fit. The insert I got was too long there is no room to screw that nut into the housing it is model 34000243. I am I missing something? I did not try to put the nut on because the clearance was so tight. My 71 has KYB Gas Adjust struts all around they are a little too stiff for me. What other options do I have for struts? Choices seem to be limited. Back in the 80's when I had my first Bavaria we used to put Bilstein HD upfront and regular in the rear so the car would not ride too stiff. My 71 can get a little bouncy sometimes even on smooth roads. Why don't these Bilsteins fit?
