A/C heater box spring

[Barraguy]

I’m looking for the helper spring that goes between the arm that works the fresh air/recirculate door. Does anyone have an old heater box or a picture of a heaterbox they may have had out of their car? If I can find a picture I can try and source one from somewhere else

I've rebuilt my ac/heater box on '70 charger. can't take any pictures now because it's installed and all buttoned up. If your box is the same their is a great thread on this site with many photos that may show that spring. Hope this helps.
