1957 Hood Hinges

The hood hinges on my 57 4dr HT are in good shape just dirty, so I blasted them shot them with a light coat of seymour stainless paint and installed replacement springs from Danchuk. The replacement springs seem to be slightly longer than the original and as a result the hinge moves backward not forward when I attempt to close the hood. Is this typical any suggestions could it have something to do with how spring has been installed. I had the same issue when I installed a replacement hinge and new replacement spring.
