Excellent JJP. Many thanks for that little tip 


I bought the entire arm replacement for under 20 bucks on Amazon. Took two minutes to replace.After searching the internet and finding out they want you to buy a whole new arm with blade. I decided to just pick up 16" all they had in stock for only $4.00 at Walmart and change the blade. Super easy and didn't even take the arm off.
Just slip the old one out by bending up on one end and pulling out. Take the new blade, cut to size, slide metal rails in new blade. Slide whole blade back in arm.
Easy as that.
Just a heads up for anyone needing to replace there. At 52000 miles mine started to dry rot and fall apart. I never use it.
Rock Auto didn't have the AR-10W but they DID have the Trico Exact Fit 10-J. Trying to find the 10" wiper currently is not available in local auto parts stores, Walmart, Amazon. I didn't check the price for the blade at the dealer because I was just so annoyed at what they gave my father-in-law for a replacement cost. They recommended a cabin filter replacement and rear wiper replacement. I don't know which was which but it was $71 and $92 for them. It was $24 for the blade and filter from Rock Auto.For those looking, Rock Auto carries a 10 inch replacement rear wiper that fits perfectly. It's the Anco AN AR-10W. It's only $4.76 (much cheaper than the Mopar). Installed in about a minute.
