W168 A class injector clamp bolts

[Locky]

Hi all.... it's been a long time since i've been on this forum. I now have another mecedes with a question. I'm repairing leaking injector seals. I bought a couple of new clamps and stretch bolts from MB but mine seems to have studs and nuts to secure the clamps. Does this sound correct or has someone tried to make a repair? It does look like the injectors have been out before. It's a 1999 car.

Thanks all
