Injector fit question for 95 E320

[puzzler]

So clearly some knowledgeable hobbyists here! Maybe somebody has experience with injector options and fit across years??

On discovering my 95 wagon was worth restoring I had some missing/rough idle and installed the quad electrode plugs which I dont reccommend. It runs much better with carefully gapped conventional plugs..Went through the ignition components and replaced some rusty and cracked parts..One coil pac..Then ended up doing the head gasket and rebuilding the head.

Running beautifully now but back when I began the project, I purchased an EBay suggested set of flow matched injectors from a california injector shop..reasonable at $125/ per six..But the part number instead of being the proper A0000788523 was A0000788623..(86 instead of 85).

The injectors appear to fit just fine and the only difference I can see is four tiny holes instead of the pair of holes in the original injectors..And checking the catalog I see these called for by Pelican for the 97 e320 which is the V six..Mercedes brand..

The supplier said injectors may vary depending on month and chassis number and different injectors were supplied for the same car..The dealer was indefinite about the question and just offered to supply the original set..part 85..I suspect the 86 design is slightly improved..

Id like to install the new set..Just wondering if any risks are associated with a possible mis-match?

Thanks again to the experts sharing the wealth of knowledge on here!
