4 speed Hump for a auto shifter

Just got to thinking how cool it'd look to hide a Hurst Vmatic or a B&M shifter under a 4 speed tunnel hump with just the rubber boot and shifter on top, I'm thinking of doing this on a front bench seat 71 Duster, Anybody ever done this? Seems like its doable,
If anyone has the tunnel demensions then I could find a cable shiter and modify things to fit

Lokar makes shifters for just that idea (common in Hot Rods and what not, 4-Speed Appearance but with an Automatic)
