Assembly CASE BASKET-FRE;RS- DA97-15043A

I'm considering this part for use in a secondary fridge/freezer that has a Freezer compartment exactly 12" wide. My model is NOT listed for this part -- I know that. I'm trying to find a bin that will fit in the space I have (currently holds a basket -- I need something solid/waterproof). Please let me know the exact dimensions of this part. Width == at top edges, Left-to-right Length == At top, Front to back (opening to rear of bin) Height == top (top edges/rails) to bottom And due to the odd shape of this one, the rear side sloping at an angle, please also provide the Length of the Bottom, front-to-back (should be shorter then the Top-edge Length. Thank you, BCA +++
