My rear wiper motor has been leaking wash fluid internally, and I finally bought a genuine MINI replacement part, but the original has a hole at the end of the shaft that mates with the blade cover and leads the fluid to the orifice in the cover, whereas the new part (same part number 67636932013) has a small pointable orifice side mounted near the end of the shaft. It looks like there's no way it would mate or work with the blade cover (61627044627). Is there a new cover that works with the new motor, or do you just leave the cover off now? Kind of want to figure this out before trying to swap it in and see, as that may affect the returnability of the part. This is for a 2003 R50, but the part is listed as covering 2002-06 R50 and R53. Pelican parts says this is the correct and only part. ECS Tuning's pics also show the new style shaft end but don't know anything about how it fits. Anybody run across this yet?
