Woes of my Model F

Originally I was going to post an awesome how to disassemble and restore a Model F Keyboard.
Anyone not familiar with the Model F, it is the keybard that came with the IBM PC 5150,
the computer that changed the world in 1981.

These keyboards go for a few hundred fully restored. They have a full buckling spring that makes a loud "clack"
and by far IMO is superior to any cherry gaming board produced today. This is the Rolls Royce of keyboards.

Anyway,
I had a key that wouldn't register. On the advice of the Vintage Computer Club I disassembled it and cleaned it thoroughly.

BEFORE:

AFTER:

This story should have a happy ending right??? ... WRONG.

After reassembly I noticed the space bar just wasn't working correctly. I took it apart again and to my horror....

I broke the capacitive buckle spring assembly.

I searched google for a replacement to no avail.

If anyone knows where to get one I'd be much obliged.
