Do you know what year directional housing is that used in your car? Does it have just the blinkers/high beam and key switch, or is there also a stalk for the wipers on the opposite side?
If it's just the blinkers/high beam, you have the option of replacing the directional switch and housing with one from an earlier car, extending the steering column, moving the high beam switch to a floor mount, mounting the key switch in the dash and doing a bit of re-wiring to bring the old wires into the new positions. You may need to change out the relays as well, but it all depends on the year of the electrics in your car.
Sounds difficult, but it's pretty straight forward, one-step-at-a-time kinda stuff.
If you also have the wiper switch in the column housing, you'll need to move that as well and will need a wiper switch from a '71 Beetle (or there abouts) and a nice dash knob to finish everything off.
An ALTERNATIVE, is to remove the key switch from the housing, rewire it to the dash, cut the metal key plinth away from the housing, and fill the hole. Sand and paint and it's done.
I've done this twice before and have just completed this change over for my 356SC since I'm using a VW wiring loom, steering box, shaft. column, switches and electrics. If you wanna see some pics, I can soot some and post the PhotoBucket links.
All in all, either way, the key in the dash is a sweet vintage touch and not beyond a dedicated do-it-yourself kinda person.
Luck,
