Fuel injector mounting bracket

Hello All,

This regards my 1989 300SE with 235k miles, which makes it the in-line 6 (M103) engine. Yesterday I replaced my fuel injectors. Which, because I pulled the fuel distributor, was pretty simple. Except for a couple minor problems:

I stripped a couple of the 5mm Allen head bolts. And I broke one of the metal brackets that hold the injector in place/mount the injector to the engine.

I can not find either part to purchase replacements.

Does anyone have the part numbers? Or does anyone know interchangeability with other engines so I can hit a u-pull-it yard?

Sometimes pictures help. Here’s a proper bracket and bolt from the top.

Here’s a proper bracket and bolt from the side.

And here’s my broken bracket and a stripped bolt.

Great! I’ll look at that part.

For the bolt, I have those reverse threaded, cutting sockets. And it was easy-peasy.

But to get the socket on, I tried to bend the spring bracket. Which is how that broke. Which gave me easy access to the bolt head. ...The socket bit into the bolt so hard it stuck. So I used it to tighten the bolt back in.

The last picture is actually after I replaced the fuel injector. It’s actually pretty snug. And will do for now. But I’d like to replace them.

...I think I lost a rubber mount for the fuel distributor too. I have a 10mm bolt that goes into a hole in the fuel distributor, at the engine. But there’s only engine there. And it feels like a gap underneath the FD.
Looks like that’s the spring clip! Thanks!

Anyone have the part number for the bolt?
...Reread that. I have at least one M6 bolt. I’ll give it a try.
