My jeep is not a J-hook arm but the locking clips on the wiper come off and i just put the clips from my old blades on the new blades and it works fine. I read alot of people have a problem since they dont have the J-hook style wiper arm. I hope they figured it out. I dealt with this problem with my truck as well and i guess redneck ingenuity helped out. The duck tape idea was my 2nd option.
