Guys, i successfully did this with the part that lewis supplied earlier on that page (thanks alot btw, fits like a glove, perfect / no leak on russian winters either)
the rear wiper is a super monster b**** to remove, seriously.
the rust caused by the winters over here in Quebec was uber, however, after like 1 and a half hour of pulling (try not to break the glass either), it pulled, i shouted VICTORYYYY all over, hahah
but seriously, if you're having trouble (surtout toi, fred) put some wd40 2 or 3 days in a row, it helps alot
i was so desperate, i even considered buying myself a dremel and cutting the motor straight LOL!
