The springs i use where from a RC car (Venom Racing Creeper) if you look at the RC Car brand 'Axial RC' you can find long size springs they don't need to be stiff or soft they only need to 'wobble' so all of them will work fine. Even some fuel line from a car would work as a 'wobble spring'

For example
-Axial Racing AXIC1297 Spring 14x90mm 2.25 lbs/in - Green (2pcs) (Blue Springs)
-Hot Racing 120 Rock Crawler Dual Rate Springs STD120MR128
