2011 Voltage 3950 pin box replacement

I'm seriously considering replacing the fixed pinbox on my rig with a Trailair tri-glide. I don't know what the pinbox model number is and more importantly what the equivalent Trailair model is. The measurements don't seem to match up to any of the boxes on their list.

I'm pretty sure it's a Lippert 21K pounds box.

Anybody know the numbers?

Thanks, Joe

    If you have a plastic cover on it pull it off and check on top of the pin box itself. That's where I found mine at.

    Where on the pin should the number be stamped? I just checked my pin box and don't find any numbers stamped on it. There is a VIN plate riveted to the curb side of the pin and that's it.
