spare tire tank

[71catruck]

So I went to install my meth kit today and I was going to use my washer fluid bottle but the part of the inner fender were it mounts actually broke lame. I don't want a normal tank in my trunk because its my DD and I go on long trips. I need the very little trunk space it has as a convertible. Does anyone know were to get a plastic tank that fits in the spare tire well. That thing is usless anyways.

You can probably get creative and make something. Use a container you want mounted back there and then fill around the rest of the way with some hard Styrofoam like they use on crab trap markers. As long as there isnt a huge void, the backing on the trunk carpet will hold up alot of weight.
