Help with installing racing seat

Just got my racing seat and the sliders that come with it (universal) are crap. They don't fit (what a surprise). Anyone have any idea how to install them in a 6th gen hatch? Here is a pic of the bottom of the seat. The red circled is where the sliders should be mounted on.

Here is a pic of the stock slider. The circled is where it is mounted.

Pleaseeeeeeeeeeeeee....I need help!!!! Would Sparco sliders/brackets work???

dont use your stock mounts, use the ones that came with the seat. if the mounts are different then make new mounts. like you can either drill new hole, or make a bracket that mounts it form the slider to the floor
