Door springs

[Donaldo]

I have been trying to purchase 2 door relay latch springs - 3 different well know suppliers have sent the wrong items and so far none seem to give a darn, they just ship what their suppliers give them - anybody ever think to check ?? Here are the differences - obviously the original, but broken, spring on the left is what I am needing - and you see what they all sent - all of them the same wrong part. Would an .055 piano wire wound into a spring work well ? TIA, Don

So while I have it apart....
