Hi I have a 1993 jeep grand cherokee limited. i just recently found out that my ring set had a chunk taken out of the main ring. i bought a used ring set from a junkyard that was in good shape out of a 1993 jeep grand cherokee with the same dana axle and the same 3.55 gear ration. would it be safe to put that ring set in with the existing pinion? the pinion has very minor scrathes to it
