The rivnuts will not hold them together. Take a couple drawers out and drill holes. Take a 1/8 or 1/4 piece of steel and put it on each side and then bolt the boxes together. The steel will capture the stress. Just make sure it's 1 piece of steel for all the holes.

That is an older Cart. I think is a rebadged snap on. Snap on sold them but I remember buying one of these, that I still have today, from a no name and it still works great even at 20 years old. Good find.
