Original wiper blades and arms??

[ellisjay2]

Local part stores have off brand wiper arms that dont cover most of windshield wipe motion, or I just havent found right store. I got a set from orielly auto which one arm completely came off while driving, and the blade lengths didnt seem long enough, should I just order a set off lmc or anyone know of a good match online?? its critical to have clear vision when in rain, being the defroster doesnt blow out defroster vents hard onto windshield.
