47-55.1 Replacing A Dash

[Dachshund]

Ok, so I have found a pretty good "low Rust" cab for my 1947 5 window. The only trouble is - someone in it's past life has put a homemade dash in it (good job - ugly dash). My question is - how hard would it be to remove the dash from my original "swiss cheese" cab, and put it in the "new" cab? I have seen the dashes for sale, but don't have the cash for one just yet. How feasible is it to remove mine, and put it in the other cab? Am I better off going with an aftermarket or should I attempt it.
I've done a search, and came up with anything from "easy", to "impossible"....
