Hey Chris, the gas can carrier I have wasn't from Calmini. It's actually a Jeeperman gas can mount that happened to fit on my Calmini bumper.

driver's side, the passenger side may not work (it def won't work for 00-04 Xterras). Also be sure that it will fit a 2" square tube at a 45* angle, this will ensure it will mount to the bar to the left of your tire.
If you want to test fit the passenger side mount I still have mine that didn't fit. I just never got around to selling it to a Jeep owner.
