Here are some pictures:

<a href="http://www.hornguy.com/benz/inj3.JPG">Here's a close up of one I believe is correct.</a>
<a href="http://www.hornguy.com/benz/inj4.JPG">Here's a close up of the one that is wrong.</a> The injecters are in there, but they are pointing backwards.
<a href="http://www.hornguy.com/benz/inj5.JPG">This is the bakelite.</a> Note that it is in two parts. The 10mm nut holds the top piece on. The bottom piece is held on with two allen nuts.
<a href="http://www.hornguy.com/benz/inj6.JPG">This is with the top bakelite piece removed.</a>
<a href="http://www.hornguy.com/benz/inj7.JPG">Lifting the bottom piece.</a> Note that the stud that the 10mm nut was on does not allow me enough space to curve the injector tubes out of the holes.
It appears to me that I need to remove the stud from the manifold before I can take the injectors out. I then need to put them back facing the correct direction and bolt everything back together.
I hope the pictures help explain things.
Thanks
Matt
