Bucket seat Mounts

[Hopchop]

I have had a bucket seat fitted to my e30, the brackets that were used you can see in the pictures attached. My seat is way to the left making the pedals seem like i have to reach to the right to hit the brake and accelerator. I looked at the tunnel side of the brackets and have about 10mm max scope to move them, I need to move it across at least 50mm. What kind of brackets have other people used on here, any help greatly appreciated.

The type of seat is a cobra suzuka (standard size)
