I got them for Christimas but the 18" windshield wipers appear too small. I received 18" and 26" wipers. I'm guessing I need 19" ones but just want to confirm.
Mine are: Drv Side 26" Pass Side 18" Rear 16". I usually just get the blade inserts which are a universal type that you snap the metal inserts off at the closest score mark and cut the blade length to match so I make mine as long as practical. (Mine are therefore 0.4 and 0.1" (respectively) longer than the above measurements.) With getting inserts IIRC there are different blade widths left and right. D - 8 mm; P - 6 mm. Not sure if they are designated in mm or inches in the States, but if I had to guess they probably would be (just under) 3/8" and (just under) 1/2" respectively. The exact measurements in mm are D - 671; P - 460; R - 400. (max 406) I don't know if that is of any help.
