So you bought all for those with a stuff inside you paid $100 for all four? The real Molly bags from Mopar are close to that and they're bigger are theyYup sure can! This is with the table down. I simply went through the spaces in the table and snapped them in.
The molle bags can work nearly anywhere in your vehicle that they can hug and snap back to themselves. To answer your question more directly in relation to the tailgate would be a Yes:
Yes you could possibly use them mounting directly to your stock tailgate as it also (as seen in the photo above) has similar space patterns, however, it would be much harder to “thread” them. You would likely have to remove the panel, thread, and reinstall the panel. The panel removal is VERY easy though.
Here ya go!
