My ’35 hood is semi buried in the attic and I can’t see the inside at the moment to see these springs. Is their purpose to be just a friction source to hold the door in any position or are they doing an over-center to keep the door in either fully closed or fully open? My doors have friction and no apparent over-center action.
I am wondering if someone has a picture they could post of one of these springs to see the configuration and dimensions?
I have ordered small batches of 10 of various springs for my Pierce if I can find a close enough facsimile, or if nothing workable custom springs can be done for a small batch with a setup charge. The last time I had a special spring quote it was something like $700 for maybe 10 springs, I managed to hand wind them myself but they were small gauge wire.
