230sl seat adjustment knob and cap

[chatntoo]

Missing my drivers side black plastic seat adjustment knob and cap for my 1964 230sl. It is round knob and not notched like the 280sl knob. On the inside it has a star shape metal bracket. Anyone have one or know where I can find one?? Ones I have seen are the notched shape.

not 100% sure if this is what you are looking for since you did not include a photo.  But if this is what you need, this vendor is very reliable and ships to USA.  Probably order a few more items that you might need to help offset shipping.  Excellent vendor.
