I think I still have the rubber ones that came with my new batteries....I don't use them as my batteries are totally sperate....I will be glad to give em to you if you will send me your mailing address....or I think I have seen some at West Marine ..... I don't like the darn wing nuts...they can come loose...and I now have a blown recifier on one motor caused by a loose terminal.... I will from now on...use nuts that I can get a wrench on....no more wing nuts...
