My 1977 Delta 88 coupe is missing the spring on the lower door hinge on the driver's side. When you open the door it does not "lock" into one of the positions. It will just swing freely back and forth. This is annoying and dangerous. I'd hate to go to a car show, open the door, have the wind take it and hit the car parked next to me. I'm sure the owner of the car wouldn't be happy either. The 1976-81 Parts and Illustration catalog lists it as GM part #20003746 and shows it was available on the 1977-81 B37, C37 models along with the Toronado of the same years. Was this spring used on other models also? Is it still available? Is there an aftermarket equivalent? I need the spring but would consider the entire lower hinge if necessary.

 

That spring was also used on the 1983-90 FWD A-body 2dr cars (Cutlass Ciera, Pontiac 6000, etc) and 83-83 F-body cars.

 

Looks like Classic Industries has the spring. On their site it is part# 20361482. I'll order one after I check out the rest of their products, just in case of the rare chance they might have something else that'll fit my car.
Thanks.
