Wood storage question

[1930artdeco]

Hello,

Priorities are changing as to cars. Soo, to that end I may start buying resto supplies for the Town Sedan. I have to replace a huge chunk of the wood in the car. I am not planning on restoring the car for a several years, but....what if I buy the wood now while I can afford it before retirement. How should I store the wood? Will it shrink over time as it dries out and am I going to have a hard time fitting it?

Thanks,

Mike
