71 K10 SWB what axles

[nickv6266]

Ok i posted on here about my 71 swb K10 before. Ive decided to just put it back with half ton axles. Someone has put ff14 and 44 front 3/4ton axles under it. Im sourcing parts for this truck now. Im putting Sm465 205 back in it and plan to put 4" lift and 35s. What gear ratio do guys think would be good for these tires and tranny? Not going to be an offroad rig mostly driving around town and occasionally to work which is 15 miles away. Any help deciding which gears would be appreciated. Probably just keep 350 in it. Thanks
