KA Speed Sensor in older Datsun Trannies

[Boaty]

Hey a buddy of mine is curious if a KA speed sensor will work in older Datsun transmissions or not.

Is there an easy way to adapt one if it's not? They would be using an electronic speedometer.

 

If it's a difficult task, I will simply recommend they use a GPS speedometer instead.

 

When I did my gauge install it sparked some interest with some people, I told them I would look into some options for them.

The later 71C speeds sensors will work in the earlier 71C transmissions that had a cable speedometer. It will also work in the 71B transmissions as far back as 1980. Earlier ('79 and older) 71B 4 and 5 speeds will work if the speed sensor is modified. This is easy to do.

Thanks Mike!

 

I'm not sure on his mechanic-abilities, if there is any write up or pictures and such I could forward that'd be great. He's not local to me.

A picture of the speedo pinion area will help. Even if it's an old tranny the pinion sleeve can easily be modified and should work just fine.

I tried an S13 71C speedo in my 71B tranny but they are way too different.

This is a 71B pinion and sleeve... I don't know what the left one above is but the right hand speed sensor should fit the 71B.
