The housings are just ABS plastic and can easily be modded. I used the set of lowbeams that I had originally purchased for highbeams in my foggies. They now sit (or will when I finish the next step, missing $) in clear 5.75" housings.
Anyway, I didnt use the mounting plates either. Mine are mounted to an aluminum sheet that is mounted to the car. It wouldnt be hard to mount them to the lamp instead. You could aim everything up and -then- seal the space. Just an idea.
And, coming from one who has used both, get the highbeams as well. They are well worth it, and it gives you the full assortment of matching Hellas. It looks better and, at least on the pre-98s, performs much better then the OEM highs.
Like I mentioned, the ECE lowbeams give a crisper cutoff and a slightly narrower beam pattern when compared to the duller cutoff and almost 180 degree coverage of the DOT lowbeam. The coverage might sound like its a disadvantage, but the lamps are stuffed into the housing, cannot give their full coverage because the light will bounce off the internals of the OEM housing. The ECE lamps use an H7 which has a lot more bulb choices/availability then the H9 equipped DOT lamp. Granted, lumens are down slightly with the H7 but the light on the road is brighter because of the pattern. The ECE lamp will also give a razor sharp cutoff which is better if you want HID.
The bad part of the ECE lamps, they will cost you about $80 more.

didnt check with Susquehanna to see if they have the ECE lamps.
