Hey guys I'm thinking about switching out my 10 bolt to a 14 bolt rear in my 98 K1500 Ext. Cab 4x4 5 speed. I was wondering what all I need to do my part guy has one with the right gear for mine which is 3.42, and has drum brakes and is a 6 lug so I don't have to change anything there, but I dont know if I would have to get a different drive shaft I know I will need a new u-joint and if anyone has done this swap before please let me know what u-joint I would need. Anymore info will be very helpful thanks.
