I just bought a 1955 second series Suburban that was originally a Napco 4x4. The PO replaced the front axle with a Chevy 10 bolt with 3.54 gears, PS and disc brakes. The original 3.90 rear end is still in the rig and I have been trying to find a newer 6 lug rear end with 3.54 gears and can't find a good match. Has anyone else found an approximate match for width and gear ratio?
