I have installed a wide ratio 5-speed transmission from a 1977-1979 280Z into my 1970 240Z and want to verify which gear shift I should be using.  I'm thinking it is 4, 5, 6, or 7.

 

 

Other than fitting through the tunnel and letting you get to each gear without hitting the hole or console, you have to use one of the shorter tipped shifters or you won’t be able to get 5th gear with that transmission. 

Many have been caught with this issue. You “think” it moves into 5th when you’re on the floor testing it, but once under power, you find out “NOPE”

Probably any of 4 - 7 but you won't know until you install one and see.  Make sure that you use tight bushings, sloppy bushings make close quarters worse.  A 1970 car is in that range where people cut and reweld their shifters or trim some of the hole or console.  

Soak those old bushings in very hot water before trying to remove and install if you're going to try to reuse one on a different shifter.  They can get brittle and its worse if they're cold and dry.

You can have your shifter modified to work. 
 

 

Seems like people had to cut the tunnel AND the console on the early 240 5 speed swap-in? Or do the modified shifter.
