Need help: Restoring HP41C

This query would probably best be answered by any list member who works with classic calculators. I have an HP41C in pretty decent condition. The problem is that, over time, the rubber pads under the flex circuit below the display, and the elastomer contacts joining the logic board to the keyboard, seem to have deteriorated enough that the thing is wildly intermittent. What's the best way to deal with these issues? Would I be better off simply replacing the two elastomer strips? If so, where would I get them from?
