Somewhat related:

I'm replacing Bilsteins with Konis and dealing with this bump-stop issue as well.  I don't have the original Strut-Nut/Threaded Cap (431 412 047 B) that holds the strut insert in the housing.  Can I use the old Bilstein nut on top of the Konis?  Does it serve the same function but just requires a different tool (I'm convinced only a 24" pipe wrench and torch would have done it) to install / remove?  The Bilstein does seem to be a substantial part and I've never seen an OEM cap.

Also:  I've only seen it referenced in the V8 thread, but the struts are the same as far as this goes.  When I removed my struts and turned them over a considerable amount of water (a few ounces) poured out (explains the extreemly rough ride in winter).  Would it make sense to put a weep-hole in the bottom of the strut housing tube to drain out water?  I certainly don't want to have a problem in the future with freezing again.  Does everyone run with nice untorn boots and does that do enough to keep out water?

The Bilsteins don't need external bump stops because they're built internal. Konis do require them as Bernie said.
