rear difflock on a 2wd

[BALDY3260]

don't know if this has been asked before, i've done a search but can't find it, so here goes.........
i would love a syncro, but cant find one in the spec that i want( rhd single cab diesel jx if any one knows of one ) however, i have a solid 2wd single cab, lowered 70mm, that i love, and with all this snow we've been having was thinking, if i fitted rear diff lock, it would maybe make it a better proposition to drive around, but don't know how much, how difficult, any reasonable benefits. can anyone give me some ideas. thanks in anticipation baldy
