drill press spring?

Quil Spring has broken on my drill press.
Existing spring details
Spring cup 40 mm diameter internall
Spring 6mmin depth any bigger would obstruct tension notches of cup.
Spring 1mm thick.
Looking on Amazon UK found lots but most over size in diameter and depth. See one 6mm depth .7mm thick 35mm diameter would this size be suited if hooked on to cup would it take up 5 mm when wre strap removed an set inner hook to fit the drill spring spindle.?
Many thanks in advance.
