Tilt or non-tilt column? They are very different. Non-tilt internal, tilt external fed by a Bowden cable. I am out of both but can put you on my Wait List if no one here has one.
Did you find a signal switch yet? As Jason stated, tilt and non-tilt switches are very different. I have both and can provide either one. Send me an e-mail. firstname.lastname@example.org.
