Please help!!! Fuel tank question
 

I have a 2000 sierra 4x4 extended cab 1500. Earlier today someone was nice enough to punch a hole in the side of my tank to steal the gas. I found another tank on Craigslist but it's from a 2wd. Does anyone know if it's the same? Also what other year/models I can grab another tank from or any solid patch ideas? Please any help is appreciated I need my truck up and running by Monday.
