After several request for these tanks I decided there were needed, so with the help of several LSPers and google, I have these now finished.
They come in two parts, as in the photos. They are "generic", so they have to be mounted on the chosen kit by your own method.
I will say they WILL require some hogging and sanding to make them fit. A hot water dip in a cup will be the easiest way to make them fit perfectly.
SO, if anyone wants to have another project let me know.
