Greetings! first time poster; I'm into a '67 230SL...JUST pulled the front shocks off, and they ARE a De Carbon. It has 3 green vertical paint stripes, and the numbers on it are: a 6 over a 66, which indicates a June 1966 mfg date, I think; a MB # 113 323 0000; and the last one long number, is 50900849390. They are very weak. My question for anyone is this: I have some bilsteins here, new, purchased long ago, and thenumber on the Bilstein is: B9760? can't make out the last number, and under that is 43001. The new shock is about 4" shorter than the De Carbon. (Jeeze, I hope they're correct...) Anyhow, these MAY be the original shocks to the car? Any thoughts? Thanks, Steve. NOT first time poster...sorry....
