Outer Limits 4x4 Board

I'm thinking about buying a SWB 3500 5spd NL paj as an offroad only vehicle but if i do, a 3 link SAS would be the first mod.

could you tell me what would be involved in this conversion?

axles off what vehicle has the same width etc? can i just cut the suspension components off the current axle (ie torsion bars etc) and weld on the brackets for the 3 link? if not what axle would you recommend to get the same axle width etc

i'd like to keep the same diff ratio's and for everything to line up nicely etc as i'm not too mechanically minded, i'm a welder by trade.

Cheers,
Cameron.
