Gq Leaf spring to coil chassis swap

Hi all I’m sure this has been asked a few times. But I’m currently looking at a gq patrol with leaf springs under it with low km, Considering buying it and just getting a coil chassis to do a swap.

Could Anyone Tell me how difficult it is? Or point me to any videos/good information I’m not very mechanically minded but have been told it’s not to hard aslong as it’s a diesel wagon chassis I’m using. I’m keen to give it a go just unsure how difficult it will be

Thanks all
