With the reference to 3/4" plate I was referring specifically to the interface between the loader and the tractor. It is hard to find good pictures of this on the internet but I did my best (hence why recommend looking in person).

But that's just one example. You really need to look at one and then the other (better yet side by side), look over the whole loader. Look at how the loader is tied in all the way to the back axle (or not), look the size of the cylinder rods and the pivot pins they use, look at the gussets (or lack of), the gauge of the metal used throughout, you'll see what I mean.
