I'm trying to determine the kind of rear axle I've got on my truck.
The truck VIN decodes to a 69 C10 1/2 ton P/U with the V-8 motor.
However the frame was cut just behind the cab and a different frame welded
on. The numbers on the rear axle are GM58 and NF 3896839. Does this give
anybody a clue as to what kind of truck it may have come from??
I know what the ratio is, 3.73, since it was stamped on the ring gear
when I took the cover plate off to drain the fluid.
Bye the way, I went to driveline.com and none of the above numbers
match anything on their web pages.
Thanks!
