Skid steer plate and latch box size

[chander]

I picked up a skid steer mounting plate and latch box conversions for one of my tractors and the plate is about 3\8" taller than the latch. My question is what is the standard dimensions of the mounting plate?
Using a framing square, I have 16 1\4 to the bottom of the plate where the plate is bent up.
I can modify either the plate or the latch but I don't want to find out this setup will not fit any other attachment that I purchase.
I know these parts are cheap knockoffs but quality control is way off.

You're welcome.

You can shim the gap like this:

I had to do the same thing on my forks....

Thanks for the ideas, that's what I was thinking of doing to modify the plate. I just can't understand why someone can not make a plate to specifications? Maybe the conversion from inches to millimeter is confusing?
