Mahlon,

Of course you buy it. Just don't pay $650!!

The springs you can likely get from Small Parts, Inc., though I have not 
run down the correct size, length or other details for those springs.

http://www.smallparts.com/

This page describes Beryllium Copper coil springs..the smallest is .073" OD 
and  .37" long.  Someone should measure the springs we are looking for and 
post the measurements, diameter and free length.  The number of coils may 
matter some what.  These things seem to be around $2 each, and I am sure we 
can find sources for much less.

On the other hand, if you extract the springs you have, treat them with 
rust remover (I have has some success with "CLR", Corrosion, Lime, Rust 
Remover) you may find that they work  just fine.
