actually, you don't need to remove the blade and you don't need to remove the metail strips. your version of the process is overly complicated. simply give the blade a tug on the end with the locking tabs and it will slide out the rest of the way. slide the new one in (being careful not to let the metal strips fall out) and when you reach the indent/locking tab, give it a little extra tug to lock it in place. that same style of blade is OEM on many cars.
