Zoom car seat buckle help

[cplus]

I had the passenger side airbag deactivation bar installed earlier this week, and the ECU reprogrammed accordingly. Now I need to fabricate a buckle to actually get the thing to work with my kids' car seat. So, can anyone help me out with either a picture or dimensions -- or better yet, both -- of the Zoom car seat buckle that locks into the deactivation bar?

I might be able to come close without a picture and dimensions, but they would be a huge help getting started in the right direction!

Thanks, and I promise to post pics of the buckle when it's finished.
