Looking for thread on VY Radio Button conversion for VX

[br14nh]

There used to be a thread somewhere on the forums about converting VY radio buttons to work in a VX - it had circuit diagrams for both VX & VY button sets, and pictures. I've been searching all afternoon but I can't locate it.... can anyone point me to it?

EDIT: finally found the thread but the pictures are missing from it. I've PM'd the original poster so I guess that's it.....
