Pismo Keyboard

Hey,

I have an Powerbook Pismo that has recieved some physical damage to
the keyboard (keys rubber pads and scissor mechanism has come off
between C and M). The sensors still work. I thought I could use bits
from an older Wallstreet keyboard I had but the mechanism is
different. Does anyone know if the mechanism on a Lombard will fit on
a Pismo (I know the whole keyboard has a different interface, just the
keys)

Thanks
