My wipers are SeaFit “Standard Wiper Kit”, Model 1207695. I purchased them from my local marine shop, however doing a quick search I see Camden Boat Store is selling them via the Internet for $69.99 each. See
http://camdenboatstore.com/product_info.php/manufacturers_id/444/products_id/4873 for info and specs.
I rate these wipers a 10 for physical fit, appearance, and quality. I give them only a 3 for electrical features/functionality. Parking is crude. I often found the wipers to stop too low so I installed toggle switches at each to allow me to manually stop the wipers at the highest position. Also, the wipers come with only one speed. I suppose you need to install an inline resister to achieve slower speeds. The wipers are a three-wire system, one hot, one park, and one ground, whereas the broncos use a funky four-wire system. As for sync, I did not attempt to sync my wipers but I’m guessing you could achieve it by utilizing the parking feature and intermittent power source to keep the wipers in check. I haven’t owned these wipers for long, and haven’t used them in the mud yet, so I have no info on durability and strength. I presume they’ll be ok. The arms are straight so you would need to bend them 5° to 10°. Motor covers appear to be painted with a high quality baked on paint. Here are few updated pictures.
