Do any of you guys have a link to the correct Springs for the early heater boxes

No link but perhaps just go to a hardware store and find some tension springs that work. Loosen up everything so you can get a feel for the action. I will check if I have a picture of what mine look like and post if so.

Here they are.

Hopefully you can zoom in enough.

Thank you. Did you take out the little top flap.

Dan22 Thu Sep 10, 2020 12:11 pm

No I did not.Mine were in good shape just needed cleaning and painting.

Good plan to not remove that front flap. On the right heater boxes the rear flap doesn't close but the front one still opens. It puts out a lot less heat then the other side, but it puts out enough heat that I wouldn't want that sneaking in during the summer. I can reach across to that defrost vent and warm my fingertips.

Anyone know how to replace this spring and any info on were I can get one.

The spring has snapped on the other box.

Anyone know where I can get the mousetrap style spring from for the flap.

Best option might be to get one from another box. Or try to repair the old one by welding it, if it broke in a repair-friendly location.

McMaster Carr has torsion springs but not the doubled up ones. Perhaps singles could be joined to make the crossover.

Misumi may be another place to check for new.
