Live axle series 1 - 2 - 3

[MattsDisturbed]

Hey guys I'm a bit new here, just wondering if a series 1 complete live axle assembly (non lsd) would be a straight swap for a series 2 live axle, also non lsd. There's a couple of series 2s on ebay at the moment and I was wondering if I could use them to replace my gfs rear axle which is cactus.

Cheers for your input
