[1971 280SE]

Hi there, was wondering if anyone knew what the name of thick spacer between carb and intake manifold on the M115 engine. This one has the Weber carb conversion that was done before I had car.. the spacer appears to be either rubber or a hard plastic. Not sure if it’s original or if it was part of Weber conversion.. called a local Benz dealer and he was of little help

Hi, I actually was able to get a part number off old part..I googled it and it’s called a carburetor flange and the part number is 1150710568 if anyone else looking for one..
