No, it's not that difficult, I replaced all of my hardware when I converted
to H4's, see <http://www.251.org/h4.html >.  I removed the old hardware with
a large pair of pliars, you have to destroy the plastic to remove them, the
plastic is just too brittle, you're replacing them anyway, so it does not
matter.  That was the hard part, snapping the new ones in is just a matter
of getting them it, so of them need a little force to pop in, but it's
nothing tricky.

I don't know how to aim 9004's, but this will need to be done after they're
reinstalled.

I only replaced the hardware on the outer lenses, you will need the
following parts for these:
QTY     VW P/N     DESC.
2       191 941 297    Headlight mounting hardware
2       255 941 141 C  Headlight mounting hardware
2     255 941 133    Headlight mounting hardware

Not sure about the p/n's for the inner.  When I purchased the hardware it
was about $50 for the six adjusters.
