Saved from the crusher by Ed Locke: a 914/6 column from a '71!
The differences between the 911 and 914 are in the mounting pads, the clamshells (no cutout), the switches have shorter levers, the bezels for the ignition switches are different, and the special surround that doesn't match the contour of the clamshell. Note the stamping in the dash to accomodate the ignition switch.
As mentioned above, 911 columns can be easily modified to fit the 914 dash. There are threads here, somewhere. . . .ah, here's one of them:
