ya, two different tanks. i can tell by looking, the bigger tank takes up the hole space. here's a good way to tell, if it looks like you can remove the rear shackle bolts without hitting the tank its the small one, if it looks like the bolts will hit the tank its the bigger one.
if all else fails, let me know i can take a pciture of both tanks for you i have one of each in the jeeps in the garage.
