Apparently, I'm the only one who didn't know that when you're converting to a 911 steering/ignition switch set up, it's important that you weld on the 914 column mount in the same orientation as it is on the 914!
The mounting holes are offset, and if you weld it on backwards, your cool new set up won't fit on your car - at least not with the steering shafts connected! Ask me how I know. (IMG:style_emoticons/default/shades.gif) Hope this is a help to someone. Attached thumbnail(s)

And that plate only works on 72-76. Early cars require a different mount.

@MB911 Ben - The chassis is a '72. I don't recall what year the 914 bracket was from. But I have swapped early columns onto my LS car and it's a '75 so maybe you just planned more carefully and never accidentally rotated your brackets?
Either way, no worries. It's fit (still just tacked) and everything worked out. Attached thumbnail(s)

Chris don't declare victory quite yet. There are two versions of the splined shaft between the universals. One is longer than the other and the recess for the cinch bolt is clocked differently. I learned this when first driving my 911 column car. It had a segment of high effort when turning the steering wheel I'll get a better description of the one that works in my car. Rory PS I'm sure you can make either work with a bit of grinding. |

The splined shaft I'm running is the one that came in the chassis and it appears to position the column in the proper fore/aft location. I'll climb under and take a look to see if the position of the upper universal looks to be in the same spot as it is in the LS car. Please let me know if you have any additional info. Thanks much! |

QUOTE(tygaboy @ Nov 6 2025, 08:01 AM) Please let me know if you have any additional info. Thanks much! I had to re-notch the shaft on mine to get a smooth motion for a full turn of the wheel. It would bind up a bit in certain places. But, my car was a bastard to begin with, having installed a '74 /4 column in the car (which is a '70) many years ago so when i went with the 911 column, i already had mix/mismatched parts to begin with.
