Ive tried a few different blades, and I ALWAYS come back to bosch. Their silicon / soft rubbers are VERY sun resistant (and frost for that matter) - and i have yet to see a better clearer wipe from another manufacturer, heck i bought the cheap ones and theyre just as good as any other, $5 a piece is NOTHING for driving safety, esp in washington.I bought these for my 77 camaro and they popped right in. The old ones had a strange flower style tab system - i had to bend them out (6 pins i think) to get old one off. To line up the blade tips I had to switch the plastic gizmo on the bosch (pop out, pop back in) .ONLY issue i encountered was they are literally about 1/2 mm higher than old ones (rubber or fitting?), and the driver side tends to get a bit wedged in under the bonnet (mine sit under the bonnet when not operated), so ill have to try lift the bonnet stopper a notch to make space (its rusted in place :)Anyway - bosch blades are awesome. Best...
