I looked at a bunch of sites that sell tanks and none seem to have one for that application, they kind of skip over that year and model. I might have missed one though. You might have to have yours tanked and sloshed to seal it, or find another good used one and have that done. I'm not sure if the sloshing compounds still hold up to the new gasolines though, I know it eats everything else in sight.

I found a good used tank for my 84 Ford Crown Vic one time, so you might be able to score one from out west or similar, or maybe adapt one from a similar car.
