im not sure i would think you would need the master kit, but i dont know what comes in each kit

 

Just so you guys know and if it ever happens to anybody else. The gears had no missing teeth, all the spider gears were fine. What we think happened was when the axle snapped and the tires locked up the gears inside didnt break but they bent just enough to mess things up. I am pretty sure the vibration is coming from the gears. The gears are vibrating which is going up the driveshaft and into the tranny. I am hoping this doesnt throw the driveshaft out of balance but I guess I will find out whenever I get the gear installation kit and get them in. I hear with 4.10s in our cars doing 65 on the highway is at 2200 rpm's, that sound right? now for me its about 70 mph and I am at 2k.

 

i thought about you this weekend, i thought it was the gears. 4.10 @ 70 ~2200-2300..not much loss on the econ
