[Spits] Rear spring with too much arch

[Joe Curry]

The springs do not differ in length regardless of whether the axle shafts
were ling or short.  That is why the cars with longer shafts sit with an
exaggerated negative camber.

  Possibly a long drive shaft spring from a 1500.
Two drive shafts on a Mk IV (mostly short)and 1500 (long) 1 inch difference
