Fatar TP100 - Lower Foam strip - Native instruments S88 Mk2

Hello there forum

I hope someone can help me here.

I am desperate to find where I can buy the lower foam strip for the Fatar TP100 Key bed. Its the strip the Hammers rest / bounce on.

I have a Native Instruments S88 Mk2 Keyboard controller.

I am currently using a felt strip from Yamaha, but its 1mm too high, and much denser than the foam strip. causing me to have less travel resulting in a lower velocity range. I am finding i have to strike the keys much harder to reach full velocity.

Any help on where I can maybe purchase this strip, Native instruments refuse to sell internal parts.
