Pictures? Not sure I completely understand what issue you're having.

If you want to spend some money and do it the absolute best way, go buy yourself a SCI seat mounting kit from kaedingperformance..... Expensive but super safe, and well worth every penny.

Another cheaper option is to have some delrin spacers milled up for the seat, a helpful trick is to do the right side 1/2 inch higher than the left to make the seat tilted- when you enter the corner it will even your seat out and reduce driver fatigue; canting your seat just a tad to the left is also very helpful.
