Just an update. Had the switch for a while, but finally had some time to install it.

All bolts/nuts are 10mm. Space is tight but I found the 1/4" sockets/ratchet worked well in the tight spaces. It really looks worse than it is.

The bolt/nut holding the shift linkage in place must be removed. The arm is grooved for the bolt in the event the nut come off it will still hold in place. Like may upper control arm bolts where they interface to spindle.

The white collar that turn simply hold the harness end in place. To remove you want to turn upward then pry out harness plug. Install is reverse of course.

When installing, just make sure the black lever is in the same position as the original and reinstall should be easy as cake.

I did not have to align anything and now she fires right up without having to mess with the shifter.
