found an 86 k20 close to where i live, just wondering about axles and the gear ratio, interested in swapping them to my 89 k5 with 4 inch lift. help please!
it would have a 14 bolt semi float and a 10 bolt front.
for ratio it could have anything from 3.42 to 4.10 depending on options.
my 4.10 axles came from a 86 k20.
