Need Help/Advice with my 4 speed conversion....finding the right Hurst competition + shifter for my M21 Muncie.


Slowly gathering up the pieces for my conversions.

Got the pedals and the transmission so far

Muncie M21 built April 03. 1969.

#3925660 for 1968-1970.

I want to know what particular Hurst shifter I need to look for to match up

to this Muncie and what Hurst linkage kit  I need  to  use for my 63 Parisienne 

that's presently a powerglide on the floor.

Any help/advice would be appreciated.

I can put you in touch with a gent that can provide a rebuilt Hurst Competition Plus shifter, including all the rods & levers.

I can't remember off the top of my head, but the tranny's changed from either having studs sticking out of them for the shift levers, to requiring bolts for the levers, or the other way around. Which do you have? Studs sticking our of the shift forks, or a place for a bolt to go in? That'll determine which kit you get.

When I was shopping for a Hurst for my 66 I noticed Summit has for a 63 but not 66. Not cheap but it gives the Hurst numbers for the shifter and linkage kits (assuming they have it listed right) so you could shop around.

That Summit kit looks like it has the 3 bolts that go through the levers into the transmission which should be correct for a 1969/70 transmission. In my Hurst drawings it shows 65-67 had the studs sticking out of the transmission for the levers to bolt to.

And if it's wrong that easily cured with the right levers that are bolt on vs. stud style. If I remember right the rectangular opening is a different length between the two styles.

Might need to show some caution on whether that shifter kit will bolt onto the tailshaft housing of the later transmission.

I'm not a Muncie expert, but I'd say that tailshaft housing is earlier than 1969.

you have a '69 or later trans, (shifter arms attach with a bolt, '68 and earlier had studs) a Chevelle Comp Plus should work and fit your tunnel

The shifter itself is usually the same part number but the mount for the shifter should be for the xframe so it sits right. Do you have buckets os a bench? Do you plan on using a stock correct shifter boot? The shift arms to but are the year of Muncie you have. Im not home now but if you google you may find a site that has all the correct part numbers for hurst shifters and what part numbers are in each kit.

this M21 transmission is: #3925660
 
Decoded it shows the following:
 
1968-1979 series
 
built in Muncie Indiana
 
built on April 03 1969
 
Input shaft is 10 splines
 
Output shaft is 26 tooth 27 Splines
 
 
My 63 is bucket seats with a powerglide floor console.
 
My intent is to make it look factory with the four speed in the existing console.
 
So Don, what you are saying is actual shifters (Hurst competition Plus) are all the same but I would need a kit  similar to this
 
to make it correct for my x body 63?

I have a feeling you're going to need a 4 speed console, as typically the left side of the 4 speed consoles are bumped out on the left allow the left to right motion of the shifter.  Reverse on those Muncie's is in & up.

Here's a 63 Impala SS 4 speed console - I grabbed the photo off ebay.

I imagine you'll have a tough time finding a 63 Parisienne 4 speed console - but they're out there somewhere.

 No worries Clint.......Consoles can be used for manual or automatic transmission vehicles with the correct shift plate (sold separately).

 

the 1963 Impala SS (identical to 1963 Parisienne) used the same center console for both Powerglides and 4-speeds. Only the shift pattern plate is different. Photo #25 shows the center console with the 

new 4-speed shift pattern plate installed. The 4- speed shifter boot is to the left. The old Powerglide shift pattern plate is to the right.

This is the site I mentioned, it has good details on part numbers.

https://www.hurstshiftersonline.com/productcart/pc/Hurst-Replacement-Shifter-Handles-Sticks-c51.htm

It has muncie id charts, according to the chart  you have a 69 & later 452. I think the only external difference is the change from a stud and nut to a bolt.

I'll ask some 63 SS Chevy people who should know which parts fit best. The shifters have the same base shift parts but some have a higher bracket where the shifter mounts. The mounting brackets also vary a bit in height so getting one that works with the 63 console and boot is important.

Show Cars sell the whole setup and they are good to buy from but you may find it a bit cheaper elsewhere. Their kit is for the early muncie with stud and nut but they may also sell one for the stud type.
