Converting a standard RZR to an “S”

I searched on here quite a bit and found a few people asking about how to do this, and most people steered towards buying a kit from SuperATV and other places. Here is my question… I have a standard 2009 RZR 50" and I have the chance to buy some stock take-off A-arms and axles from an "S" model for very cheap. What else would I need to complete the conversion? I know somehow i would have to extend my tie rods, brake lines, and shocks. I am trying to not have to buy new shocks yet. I have seen an extended brake line kit, but nothing else.

I also have the adjustable 1.5-3" SuperATV lift installed on my machine right now. Will this have to come back off? or can it stay/will it help with my shock reach?

Thanks for any info.
