Fuel tank

[Brad]

Is a Lincoln LS gas tank compatible with the Thunderbird? Bonus question, are all years the same?

I did some checking and here is what I found on Ford parts site.

The Lincoln LS 2000, 2001, 2002 gas tank will fit 2002 T Bird part 1W4Z-9002-AD are the same.

The Lincoln LS 2003 up will fit T Bird 2003 and up part 4W4Z-9002-AA.

There are some used gas tanks on eBay.
