Bosch Wipers

[US to CDN SVX]

Silly Question. My Orig Subaru Wiper blade Supports collapsed after 16 years so I can no longer use the inserts. I put some nice new Bosch blades on but I find if I use the Summer mode the stops are no longer there so it looks like I might tear the blades. Thus I must adjust them up a bit. Same with the rear. When I open the trunk it hits the wiper.

Did everyone else just adjust the blade positions so they can use non standard blades? I guess I can just pop the black covers off the screws and adjust? Any specs on the proper heights?
