i have a brand new one still in the package. I ordered 2 instead of one--still don't know mhow i did that. ir has a ball on top and a ball in the middle. i can give you the part number later when i'm home.
THE P/N IS RAM-B-309-RU on the outside of the package. the inside of the package on the instal instructions reads RAM-B-309-1. IT COMES WITH 4 LONG SCREWS. 2 are for the wing are 2 are for harley. different thread count. i'll mail it to you for $10
