On my 1973 factory shifter there is a spring missing that pushes the handle in the 3-4 gate. this is the gate that controls the neutral safety switch on the trans. I have no idea what type of spring goes in there. Thanks for your advice.

That's the spring for the T handle for the reverse lock out. I dont believe there is a gate spring in the factory shifter . I'm positive that Hurst shifters have them though

Are you talking about the narrow spring that drops into the top of the shift lever, underneath the shifter ****?
I have the coil spring that holders the reverse T handle. The shifter handle needs to be spring loaded into the 3-4 gate. This creates neutral. The spring I think goes into the shifter housing At the tail shaft housing. I was thinking a flat piece of spring steel .

Reason: Miss spelled worf
a stock Muncie shifter has no spring to push it into the 3-4 side or the 1-2 side. The neutral safety switch is on the clutch pedal. Please explain exactly what the problem is that you are trying to correct.
This is true. The only spring is in the shifter handle as described. As MelWff said, there is no spring there and that's why you can 'rattle' the **** around in neutral. Pushing the shifter **** in 1-2, then 3-4 requires no spring action whatsoever. The three gates (Reverse, 1-2 and 3-4) are lined up with a 0.644 inch wide gauge.
This is interesting. I cleaned the grease and debris out of the shifter. I stoned all of the moving parts and reassembled the shifter with no lube. I made the 1/16 by .644 gage plate and adjusted the shift rods. It works very well now. On the munice 4 speed, there is a pipe tapped hole under the 3-4 shifter shaft on the trans. This I think is the neutral safety switch. I have had a number of hurst shifters in other cars, and I am used to the shifter handle being spring loaded. If no spring is required, I will learn to deal with it. Or I will fab a piece of spring steel and install it to create the feel I am used to. So... if the safety switch is in the clutch pedal...what is the pipe tapped hole used for? What goes in it?

You will get used to it. It takes a little bit, but you'll get used to it. I like the reverse lock out better than the hurst hard "reverse slap"

Ken, if you are asking about the sensor/switch in the circle below, I believe it is part of the Emissions Control System incorporated in some of these cars.
You will find quite an extensive discussion of the different systems and how they interact in this post... https://www.corvetteforum.com/forums...spark-tcs.html There is a good picture of it in post #6 (Transmission sensor/switch).
My '73 also has this switch, but the TCS/CEC is not installed on my car so it is not connected to anything.
