well while i do know a little bit of info on cars i do not know it all. but this is whats up....i blew out two spider gears and my pinion and ring gears in the differential of my 1980 Datsun 210. now i have to fix it. searching in junk yards has proved to be a crap shoot so far. it seems i cant find anything. maybe it is my lack of knowledge on what kind of differential is in my car? i know that it had 3.70 gears and that is about it. i need to know if someone here maybe knows what kind of diferential might fit this car. i have tried looking on the diff. and i cant get any info from it. please help if you can.
