Hello everyone. I am having trouble finding the correct windshield wipers for my 1994 RRC SWB. I understand they are 18 inches, however I have run into two problems. First, most wipers do not seem to have a nipple like projection which locks the wiper blade onto the arm, and therefore after a few swipes of the arm, the wiper works it's way loose. Second, the "J" part of the wiper arm which attaches to the wiper blade is either too narrow, or the mounting part of all the wipers I've tried is too wide and thus, once on, there is excessive play of the wiper. For example, when the wiper is sitting on the glass and is turned on, the entire blade pivots too much forward and backwards with respect to the direction of the movement. As I'm writing this I realize how poor of a description it is :roll:. Of the three wiper blades on the car, the only one that seems to properly fit is the rear and it says "Trico 8mm" on it, but after searching online I'm not able to find it. I've also searched online for anyone with a similar problem and can't find anything. I also spoke with Atlantic British and they weren't sure if their wipers have the projection to lock it into place. I hope I'm not the only one with this problem. Any advice would be greatly appreciated! Thanks in advance.
