Alfred,
it is indeed. The problem with looking for parts in EPC is exactly what you say: there is no sleeve on the drawing, you have to go through all parts descriptions on the side of the drawing and look for parts without numbers - those are the parts that are there and they are not on the picture. I could not find this sleeve and I asked the question - I was given a number and a lead that it is under W114. Another example - underdash drain hoses - great weekend entertainment.
Radu,
Yes, I cut the clamps and ground them on a grinder.
Thank you for your kind help - it was great. I just finished. I thought of a system of wood wedges and a couple of carpenter's clamps (priceless for the front bracket). I started from the left side then moved to the right side, so the middle came up pretty straight. I spent 2 hours on the bottom screw of the front bracket. I twisted my arm again (just like when I was fitting the rubber breather/cooler sleeve), I was late for lunch again (with severe consequences as well - cold fajita and silent wife), but I did it. Well, silent wife may not be that severe, actually...
