Tank Cover for 97' TCAT Please? Any Condition.

I cut the bottom bit off the underside of the factory tank and plated the top to make a circa 1.5ltr fuel cell; that fits where it origionally did (with some supports I made). I now need a fake tank cover to go over the top... I've seen a few online but mainly in the US. Anything good to damaged would be appreciated?

I have hollowed out the old tank shell with a grinder but I think a proper cover would be a better option.
