I will give you my 2 cents

When rubber parts are manufactured, they use petroleum oils for solvency, which I believe also provides a level of pliability to the parts

With time, the petroleum oils evaporate (or leach out) out of the rubber.

I would suggest soaking the rubber parts in a non detergent motor oil- i believe that this will soften them up, without degrading the rubber

A harsher solvent like laquer thinner or reducer is too light and will not leave any residual oil in the rubber.

FYI-I do all of my own work on cars, have worked in the oil industry as a Chemical Engineer in both the plant, R&D, sales, etc, and I love this stuff- I have been rebuilding a 911 for the past 7 yrs.

My 2 cents-good luck
