i recently shattered the pinion gear in my 76 k5 with a 10 bolt rear end and i am not able to spin the tires to find out what gears i have any suggestions on what my possibiolities are of finding my gearing its got a dana 44 in front and a 3 speed tranny and a np 205 tc if that helps thanx for your time

 

there should be numbers stamped on the ring gear unless you totally exploded that thing. if thats the case just open up the front axle and see what gears are in there
