300E 1986 Fuel Injector Holder PN

Anybody know the OE part number of the metal clamp that is used to hold down the injector seals in a W124 1986 300E 103 engine? I know the style was changed in later models, not sure what year. Mine has 5 clamps of one style, and one that is different. Please see pics for more details.

Right now I've got five older (original) style seal holders, and one newer style holder. I know the newer style was not meant to be used for the seals used in my injectors because the seal where that newer holder was installed had obvious signs of uneven pressure points on the contact surfaces between the two.

Vielen dank, thank you very much.

By any chance would you happen to know the PN of the screw that attaches this clamp to the manifold? It's a 5mm hex head screw. I had to chisel one out that had been tightened way too hard, and destroyed it's head in the process.

Not meaning to get in the middle of pawoSD's thread, but I read the EPC differently than he does. It appears to me that the bracket part number is EITHER:

1) 103-078-00-43 if your engine serial number is up to 061402

OR

2) 103-078-05-43 if your engine number is 061403 or higher.

The part number for the screws that hold the injector clamps to the intake manifold is N000912-006004. Six of those screws are required.

My engine is 12-027nnn, so then it seems the correct part number should be 103-078-00-43.

Thanks for your input!
