Chris, I don't think it's a 'spring'. I call it a 'detent' which helps hold the door open half or full open. They get rusty or dry and want to drag. Try spraying WD-40 or lithium grease on the door hinge and see if that helps.

 

Chris, I checked the Danchuk catalog and did not see the detent or spring listed, only a complete hinge. The spring is riveted to the hinge so it could be replaced if you could find one, In the meantime try greasing it with white lithium grease to quiet it down. Good luck with recuperating from your hip surgery. It is amazing what they can do today with joint replacement. I bet you miss banging the gears in the 57!

You need another good used hinge.

 

I think I'd try the WD40 first....may not be broken. :bowtier:

I do not recall a spring there either, lubrication first

 

It is a flat spring and does detent the door open. If it is broken, you could try grinding the remaining part of it off at the corner with a burr in a die grinder. It should break off at the corner after a little grinding. That would keep it from snapping when opening and closeing. You can replace it at a later date, just have to hold the door in the open position in the mean time. I thought the detent springs were available but can't find them now.

 

check corvette central or paragon corvette. 58-62 corvette uses the same detent spring .

Thanks everyone, that is what I will do, grind and break it off. I am driving my 57! I could drive after 2 weeks! --------------------------------------------I had a amazingly fast recovery with the new hip. I could walk 100yds easily 6 days afterwards. It is 7 weeks now, I walk a 1 mile a day for excercise. I think I was very lucky! It was a Zimmer brand cobalt steel ball and socket, plastic material sandwiched in between them. Old school but that is fine with me. I can not tell any difference at all in how this one feels and the good original! But I am still being careful for awhile, they can dislocate in odd positions such as upside down rolling around under the car. Thanks all!

 

I found one broken off one of my front doors. I replaced the entire hinge with a used one as they are rivoted in . Jim
