The cargo case from the donor Kawasaki will be mounted on the deck lid and will also serve as a portion of the seat’s back rest. The Kawasaki was equipped with an adjustable sliding base which will be used on the new trike to provide some flexibility in the positioning of the cargo case and allow for a bit of fudge factor when the rest of the seat is constructed later. The slider base is a little too long to fit in the deck lid so the front legs will be cut off approximately at the red arrows. (Photo 1)
Rear mounting brackets for attaching the case to the base are made by welding flat stock to angle iron. (Photo 2)
The front of the base frame will bolt directly to a cross member in the deck lid and will not need mounting brackets. Photo 3 shows the underside of the installed slider frame. The rear mounting brackets are indicated by the red arrows and front mounting bolts are indicated by the white arrows. In this photo you can also see the slider release mechanism which allows the case to be moved forward or backward.
