Muncie Shifter Assembly Spacer/Bushing Identification ?

[XXXGoldL34M20]

Hi Guys, wanted to know what this MUNCIE Spacer or Bushing is called?
I have a shifter assembly missing this and want to buy it, looked all over eBay but no luck. It is made out of a hard type of plastic.
Any help much appreciated as it is for a member here and I would like to get one for myself too.

it is a rubber donut that goes on the main shaft bushing between the shifter and the mount bracket

originals are hard to find because the rubber gets hard and breaks

I don't know if anyone repops them

Some people make new ones from rubber grommets but its not the best solution

Thank You Joe,
Your right mine used to be a rubber donut that dried to a hard plastic and broke apart in a bunch of pieces.
I made a spacer donut that fits perfectly myself, bottom is a thin rubber washer, middle is a outside hose rubber washer and the top is a plastic nylon Oil Pan washer.
The fit is dead on in thickness and the center hole fit is dead on.
Better then having nothing.
Can't believe no company makes this out there oh well.

Can someone send me some very good drawings or an original part? I may be able to do something.

I can get the dimensions but its not just a simple washer shape

it has a groove on the outside diameter

the inside diameter is undercut to lock into the bushing

this is what was left of mine after it dried up LOL
the orange dust cap is fine

If you can send me a cross section sketch and measurements I might be able to make it.

Not hard to manufacture. I made a few out of hard plastic. Easy matching. Any steel or plastic supply houses have it or McMaster Carr.

Someone that has a 3D object printer should make these easily buy replicating a real one IMO (Do a color like this so you can keep on eye on it)

i pulled some dimensions off an original one

i just found a mint original bushing for my muncie shifter. i will look more in my box of bushings.

[JoeC]

some of the small parts can be hard to find

the rubber donut

the ring shaped spring that goes in the orange cup and the control lever spring and retainer are often broken or missing

I'll get on this Monday and see what I can do. How hard does it need to be?

I made one out of a shock absorber rubber. Put the piece in the freezer overnight and you can drill it, grind it, file it whatever to get it to the desired size. 29 years and still working. Gunsmiths use this trick to file fit a custom butt stock to fit the shooter👍

A guy posted in my club about this too and shared a link about this Retainer which carries the GM part number 3923544 here,

Number 7 Shift Lever Shaft Retainer 3923544

That drawing shows the replacement of the new style reverse detent with the old style.

On that drawing , they don't show the neutral gate spring or what Chevy called " the control lever spring" .

I have been trying to find the original drawing that just shows the original style reverse detent to see if the neutral gate spring is shown.

The 3 speed Muncie shifter drawing shows the neutral gate spring


This caused a problem.

I did a Muncie shifter for a 68 Camaro that went for judging at the Camaro nationals and they told the owner that the 67-68 Camaro 4 speed did not have a neutral gate spring. The 3 speed did have it but the 4 speed didn't have it and they used that drawing as evidence.

The same basic design 3 and 4 speed Muncie shifter was used in 67-68 Camaros, 68 to 72 Chevelle , 68 to 72 Impala , and 68 to 72 Nova

I had many original shifters that had the neutral gate spring but some were missing them but other parts go missing on the used shifters also.


I talked with the Camaro judges on it and sent pictures of original unrestored shifters with the neutral gate spring and they sent me a picture of a NOS shifter without the spring. They stand by the rule that the 67-68 Camaro 4 speed did not have a neutral gate spring.

I stand by my findings that they should have the spring.

Most shifters use a neutral gate spring including the Hurst shifters and most of the cars and trucks that I have seen have one. Some cars don't have one though.

Shows the Shift Lever Shaft Retainer 3923544 really well
