FINALLY got it figured out. turns out somebody did some grinding and damn near rubbed that letter code off. I cleaned it, hit it with black spraypaint, and lightly sanded it. then it started to show. I know the insides have never been changed and the magic code is a C now acording to what ive read, thats a 4.10, widetrack, open, amc-20...... now that I know exactly what I got is that a decent axle or should I look in to swapping it with something else???
Give me your thoughts
Thanks
