Re: '61 K10 396ci
KOOL truck I'm not sure what your stock gearing would be but I bet it would be low gears, that truck originally had a inline 6 or a 283 maybe even a v6, Wow I just named all the possibilities, being 4x4 and not made for speed back then, course that's assuming that it's still stock running gear...if it hasn't been messed with you might find a small metal tag that's bolted to the front cover...that will list the # of teeth on ring and pinion...
example 41:11 divide that into each other and you got 3:73's..I don't know if I helped you or confused you....I'm sure others will chime in and gladly help...Oh and I really like that winch bumper....
