Funny to see that they fit, as I believe the wheelbase of an e9 to an 2000cs was longer.
In addition, the innersill has a small tab welded on the front of it to make it longer. I heard that this basically was to 2000cs part, with extra length added.
I therefore assumed that also the outersill was longer.
Before you send them out; could you please check if they are chromed steel or brass, or stainless steel?
