This is one pair of quick coupler plates for making attachments to fit Yanmar VIO35s. No pins are included at this time but will be available in the future. These are best used spaced 5.5" apart between them. This allows for plenty of room to get the pin grabber in between. They are setup for 1.5" pins 7 inches overall length. We just use round bar welded in as shown in the second picture.
