FYI:

I found out why i could not get a rear frame w/ blade at the local auto shops. I went to the local bimmer dealer (great place in MPLS, Sears import!) and they had the rear frame w/ blade unit for me. Then i asked him about how my rear wiper blade unit connects by pushing on it or taking it off by pulling up on it. The parts tech then said that i had the old style arm (plastic) which broke a lot during car washes in the winter time (cold plastic and hot water, cracks/brakes). He just sold me a univ. blade and i just slide it on and cut the left overs in mins. Great price w/ the cca card, ~$2.75 (w/o card it was ~$4.75). BMW does not make the frame w/ blade for the plastic arm anymore, so one either has to just buy the metal arm (upgrade) or keep buying the rubber blade and use the old frame.
At least i know if the wiper arm cracks i will need to buy the metal newer arm. I will just wait...to many other "fun parts" i want 1st.
