Was looking for a spring for another project and saw these on this plate hanger for $1.98 at Wal-Mart...2 springs for less than one from Ace...got it home and it occurs to me the springs will work well for a vise material holder and that the hooks should work for the Detached Extended Body pins referenced above.

What do you think....the price sure is right?

They do come in 3 sizes.
