TR6 seat diaphrams

[Joe Flake <flake@a3115jmf.atl.hp.com>]

Overall, the seats in my TR6 are in fair condition,
but I recently tilted one up (chasing a dropped screw)
and took a look at the bottom of the seats.  The
rubber diaphrams are starting to go -- some connection
points torn, others on the way.

Is it reasonable to replace JUST the diaphrams and
postpone the eventual full seat cover project?  Or
is that just a waste of time and money?

Thanks in advance for your help.
