Where can I get seat side mounts for GT3?

[youngwill100]

I want to raise the seat height in my Mk2 GT3 (as I'm somewhat vertically challenged). It has the bucket seats fitted, which have side mounts onto the seat rails. Does anyone know where I can buy higher side mounts? And are the OEM bucket seats Sparco?
Thanks
William

Seats are Recaro's.... Try Demon Tweeks??
