I bought a new pair of front shocks for my '79 450SL and now every time I go over a small pot hole or rut in the road, the front end hits bottom. Its like I'm driving over railroad ties. The number I bought is B36-0707. My old ones had the number 1073230100 stamped on the shock, but I can't find anyone that carries that one. Oh, BTW, my old ones say "Made in West Germany".
