68 rearend information in a 59 Apache
J 22 8 / CON1 / GM 54 / TR 11 21 W 2 / NF 3896839
Info someone told me:
3896839 looks to be from a Chevy/GMC truck ,your's would be a 68.
The TR shows 68-69 Chevy series 10,4x2 3.07 non-locking.
This is not the same as the car 12 bolt.
I lifted the rear wheels off the ground and the tire rotated 10 times for 13.75 rotations of the driveshaft. I came up with 3.73 posi if I did the calculations right. Can someone tell me about this rearend? Is it strong enough behind a 454 slightly modified? Just curious as I don't really know anything about the rearend. Is it better or worse that a car 12 bolt?
