I too have a 62'C10, a friend of mine swapped his rear end for a 72'(5 bolt). He said it bolted right up with little to no modifying. Also here is a link, just type in your vin number, and everything from paint codes to rear end gear ratios.

But i really want to keep the 6 bolt rear axle i just want to switch gears in it. What gear ratios are available for 62's? and can i get them off any other vehicles?? from the 60's?? or do they just sell them new?  | | |

On the 60-71' are all 6 lug, and 72' was the first year of 5 lug. The 60-72' has the same frame, coils + trailing arms in the rear. 1960-62 had torsion bar in the front suspension, and 63-72' had coils in front.
These are the rear end ratios for 1962:
3.90:1, 3.38:1, 3.90:1(RPO), 3.38:1(RPO), and 4.11:1(RPO)

There is enough good in the worst of us and enough bad in the best of us that it does not behoove any of us to criticize the rest of us.
