I assume that was the early body style shown in your sig?  Maybe that matters.

I used the 280Z 4 speed shifter on all of mine, it swaps right in.  Never tried the ZX shifter.

No, my '74 frame was always manual so I didn't make any alterations to the tunnel. I don't remember if my 260 even had a transmission when I got it. I did the turbo swap first thing. I have a wide ratio 5 speed and don't like the gearing so I'm running a close ratio ZX transmission. 

The auto trans swap we did in a complete 260/280 frame was the 1975 all original 280Z from PA Museum car. We removed the original stock console, removed all the auto transmission specific hardware and trim, cut the forward part of the trans tunnel along the top sheet metal line, installed a 71B 5 speed with new boots on the trans, trans tunnel, and console. 

You can't tell from the inside that it's a swap, you can from the engine bay.

In Wheeler dealers they changed the auto to a 5 speed transmission in a 240Z. They show cutting out the floor piece and installing the shifter. Watching it might help?

Definitely. Confirms not only the cut but all the stuff I’ve done up to this point as well

You also have to disengage the neutral safety switch by jumpering it at the harness. Right next to the backup light harness.

@Yarb I left the kickdown solenoid leads unconnected, jumped the neutral safety and made an adapter for the reverse switch which kept the original harness intact. Cutting the hole in the tunnel is the only irreversible change I’m making for the swap. This car is low miles and no rust (my grandma bought it new) so making sure if someone wants to restore it someday they could. Keeping all the original parts too. I can’t imagine someone putting the auto back in but a true restoration could be done if they wanted to
