laptop key caps

Anyone have a east valley good purveyor of toshiba satellite key
caps/mechanisms?

After having called around to toshiba's support in the valley, I
*might* get lucky via spsi-az.com, but it's not at all conveniently
located near me.

I'm pretty sure any satellite keys could work based on an old model
that's not mine to cannablize. In particular, I'm looking for f3 and
f8. :-)

Thanks,

David
