The 3-speed used a column shifter attached to the steering column. 4-speeds and 5-speeds use floor shift mechanism that is integral to the transmission itself.

Overview

Shift Knobs

クシフトノブ

8mm x 1.25 threads

The stock Datsun 1200 4-speed knob is black.

3-speed column-mounted shifter:

If you want just the pattern on top, you can buy those from Autobarn and other similar stores as a badge with sticky back.

Shifter Bushes

The bushings become dry rotted,broken. New ones restore your shifter for tight, precise shifting again.

I got tired of the shifter in my 1200 flopping around, so I changed the bushings. It took about 5 minutes. I don't know what happened to the old bushings, I didn't see any in there at all. It was nice and tight last year, but one day it just started flopping. I reckon the old ones shattered into a million pieces. Anyways, for 5 minutes and 5 dollars, it sure works better now.

About $10 USD from Nissan.

Complete kit with rubbers

Top: two plastic bushes, stock type.
Bottom: Racing aluminum bushings for better control, but transmit vibration.

"Head" bush at the end, regular bushes on the side of the hole

Short-throw Shifter

A short-throw shifter is longer below the fulcrum, so you only need the move the shifter a little to move the gears a lot.

Of course if the fulcrum is higher up on the shifter, you need to move the fulcrum mount point on the transmission up higher to match.

Discussion: How to make a short shifter

Simple Method

Lengthen the shifter bottom section: cut just below the fulcrum pin in the round part. Then just weld in a piece of 3-4mm steam pipe 1 - 1.5 inches long then weld the fulcrum back on top. On the stick cut the bottom off and exten it the same amount and then weld the ball back on.

Or instead of modifying the 56/60-series shifter, use an L-series shifter (which has a higher fulcrum).

To modify the transmission, bolt extension plate on the shifter brackets:

Pro Bracket

Angelo made the adapter and stick to move the fulcrum point up about 1.25"/32mm. The stock shifter moved about 6-7" from 1st to 2nd, now it moves only 3". Side to side movement is still the same as before. It has taken me a few days to get used to. The throw is so short, it's difficult to go from second to third and from fourth to fifth. Tap the original holes for the fulcrum pin with an M10x1.5 and used short flathead/countersunk M10 screws to mount it.

Another version:

63/71 Shifter

63-series and 71 series already have a higher fulcrum point. Some later 71-series are adjustable for low- or high- fulcrum.

1984 adjustable shifter re-bent similar to 1200 shifter:

Pictures thanks to DatzenMike.

Adjustable, just reverse the plastic insert to fit different transmissions:

There is a difference in pin heights on the FS5W71B transmissions.
4-speed & 5-speed up to 1980

4-speed & 5-speed AFTER 1980

Some FS5W71B shifters from 720/S110 in multiple lengths

The two plastic bushings and the spring inside can be swapped upside down to move the pin hole higher up to move the fulcrum point up.

Interchange

These all interchange. Bends/length differ.

56-series shifter
60-series shifter (both 4 & 5-speeds)

The 63-series 5-speed shifter fits deeper into the transmission, so does not interchange. CONVERSELY, the 60-series shifter does not work well with the 63-series 5-speed, as the length of the shifter from the crossbolt to the plastic pivot point at the end of the shifter is about 10mm shorter. But 60-into-63 might work in a pinch.

The B310 floor boot is different:
