I bought 2 ea 12 volt from an Ebay supplier but called and got them a little cheaper direct, thinking about $120. Haven't install yet but existing hole needs to be drilled out to maybe 3/8 or 7/16ths, shafts are long and will need to be cut and they will need to be wired together or switched separately. They came with arms and wiper blades but blades are a little cheap. Unknown if they are still in business web address and phone off box
