The same question was raised at armourer's school and the answer was no.
Regarding the folding stock of the Mini14, it should fit - provided that the stock and the receiver were both made prior to 1997 or after 1997. Sometime during 1997 Ruger changed the dimension of the Mini14 receiver and earlier folders would not fit. Even my instructor was surprised to learn of this development. Goes to show, engineering and production doesn't necessarily tell customer services what happens on the factory floor.
