You need a swivel socket of the appropriate size (12 mm?) -- that is, a swivel that has the socket on one side, not a separate swivel. One the proper size for the wire nuts will also be helpful.

That and a long extension will allow glowplug changes without removing the manifold. Much less time consuming. There will be a way to reach all of them -- probably some under and some through the manifold.

You have plenty of room in the SDL -- kinda tight in the 300D!
