There are some differences between the early 1st design muncie and the later

2nd design muncie, One difference is early and late syncro rings and syncro hubs

you can use either one, but you must use the correct ring with the correct hub.

the picture below shows you where to measure across the hub the early hub measures

1 1/8" across and the late hub is 1" across. now look at the syncro ring picture

look at the top part of the ring on the left side,directly behind the pointed

engaging teeth the ledge of the ring comes out about an 1/8" then it steps down

and comes back another 3/16" or so,this is the late ring,it is used with the

narrower 1" hub. the ring on the right does not have this stepdown and is

used with the wider 1 1/8" hub. Also i get asked alot how do you tell the

difference between the (M20,M21) and the M22 transmission, you can not really tell

by looking at the case ,the difference is the actual cut of the gears,you can see this

in the picture below, the M20 and M21 have a much greater angle to the teeth of

the gear and also will have a twist in the teeth (helical bend), the M22 gear is a

more straighter cut gear teeth and also thicker and wider gapped teeth very

noticeable in the picture.

Here are some pictures of the new Muncie supercase

and the new Muncie super tailhousing, The new supercase

is cast thicker then the original, it has thicker mounting ears

they are also boxed in preventing the ears from breaking off

like the original cases did. the case is also 3/16" overall longer

then the original, allowing us to use a wider front input bearing.

The case also comes with the new front bearing, drain and fill

plugs, The case also uses a metal soft plug at the front where

the countershaft ends, preventing any leaking of oil down the road.

The new Super tailhousing is also cast thicker then original and

you will also notice the heavy duty ribbing on the top and bottom

of the tailhousing making the whole unit much stronger.
