Swap can be done in a weekend if you have everything ready. Remember too, that you don't know what kind of shoddy work someone may have done doing their swap... If you do find one... first thing I'd do is is get someone with some experience to go over everything with a fine tooth comb.... and then LOCTITE the fuck out of every single bolt on that motherfucker... because they will back out (even if they have loctite)
