Rob,
It has the original dated tank but it has a pretty good dent in the bottom of it and likely isn't worth saving. I do have one other original but too early of a date to use for this car. I was thinking of running a new Spectra tank until I find a suitable original with a later date. If you see a late original out there please keep me in mind or reach out as I'd love to find a better one for this car.
Here's the early one that a friend passed along to me a few years ago.
