Vintage Simmons Drums (UK) Users Group

Hi, Does anyone know how to fix a selector pad. Some of the triggers 
are not working at all but five will. Is there some way to modify it 
with triggers like the ones in the simmons pads or can you get a new 
trigger pad for it. I don't know if you can find them anymore or not.
Can someone help me with this.
