Muncie m21 yoke question
« on: May 29, 2023, 08:17:36 PM »
I have a muncie m21 with a 31 spline output shaft. I'm trying too match up a yoke for this. Getting a little confused while hunting out the right part. I see yokes for 32 spline muncie but not 31. A 31 spline output would have 32 spline on the yoke, but the way they have it worded sounds like they are talking about the shaft being 32 spline not the yoke. Has anyone been through this? Worst comes to worse I order the part and return if it doesn't fit. Just thought someone might bring some clarity on this.

I always thought the M20/M21 took the same yoke as the TH350/3 speed Muncie.

They do, but a shop in Boston built this tranny it has heavy duty syncro gears in it, they are as heavy as the m22 but have an angle like the m21. And it has a fine spline output shaft
