Difference in gas tanks

[tonyiiiafl]

Doing a dumb thing, I poked a hole in my poly gas tank. With a sawzall, cutting the lower track bar out to replace without dropping the tank. So, I need to replace the tank.

What is the difference between Mopar part

68034793AB​

68034793AA​

68034793AC​

all seem to be same. I found quite a few used as new is discontinued.

Thank you
