should be easy-ish, measure the ashtray and see if a uhf will fit neatly in there, checkout how the ashtray mounts to the dash, bend a piece sheet metal/alloy to make a bracket to attach the uhf to the existing ashtray mounts, bingo! you're a fabricator. edit: many uhf come with a mounting bracket but you might have to drill some holes to match what's already there.
have a read of these threads (and, personally, I like the gps to up on top of the dash, in the right hand corner)
