Unfortunately, they only sell the adapter with their lights. Can't purchase it separately.
In studying the assemblies closely, I believe all that is needed are the euro wiper brackets. The motors mount to the bracket with a single 17mm nut. Put the left motor on the right mount and vice versa for the other side, add a set of euro arms and your in business. Might also require a pair of fill panels, which would have to be drilled at the proper location as the wiper shaft on euros is in a slightly different location. Easy DIY job.
