[Duo2400] 230 "heatsink" in a 280

I'm considering the same type of upgrade.

To quote the service manual, pp. 59-60:

<<
Replacement Caution: If you replace a CPU stiffener on a PowerBook Duo
210, 230, 250, or 270c, make sure you install a small foam heatsink under
the tabbed area of the stiffener. Turn the stiffener upside down, align
the edges of the heatsink with the lower right corner of the tab, and
press the heatsink on.

If you replace a CPU stiffener on a PowerBook Duo 280 or 280c, make sure
you install a large foam heatsink under the tabbed area of the stiffener.
Turn the stiffener upside down and install the heatsink on the entire tab.

Failure to install the correct heatsink could cause a short circuit and
blow out the logic board.
>>

It shows an illustration of a larger heatsink than on the '030 cpus. I
suppose you could get a sheet of the material that they used & cut out a
piece that would fit over the '040 or PPC. Anybody know what material that
might be?
