I have a '65 and a '66 W110 200D's (OM621.918) that could use new pre-chambers.
I understand they're NLA from M-B, but can others be used too?
Is a p-c from a later 200D or 220D that different?
Thanks for any input.

After much research and several side-by-side comparisons...I've found there is no interchange for these little buggers.

There should be some somewhere. There is an on site antique section you might ask if anyone knows where.
