Need name of part that holds door open on 71 Scamp!

Well I just replaced the hinge pin and bushings on the driver side, and the passenger side hinge pins and bushings are in fine shape, its just that on both sides the spring snapped (dont even know how it hapens but it did)...Would it be okay to use used hinges off the dodge pickups, or would i be better off buying the refurb kit that 70duster440 mentioned...it would be great if you could just buy the spring seperatly, but no so far knows where to get em
