Anybody gone from a low performance, piece of crap Sag to a Muncie lately? I'm about to put an M-21 in my 69. Anything I need to change like the clutch size, etc??

Shifter needs to be changed, be prepared to open up the hole in the floor. The Hurst shifter used in 69's need a bit more clearance to the drivers side than the ones used on the Saginaws

I changed my 67 rs years ago.
I first used my old muncie shifter.
The linkage can be reworked to fit, if the muncie has the same size slot where the shift arms fit. There are two sizes short early, and longer slot late, around 68 was the change, and some had studs some had bolts holding the arm to the trans.

The muncie shifter is crap anyway. Mine jammed several times due to grit getting inside the reverse spring plunger inside the shifter. I had to dissasemble the shifter to make it work again.
I put a Hurst competition plus shifter on it later and it works great.
I got the model that is for a console equipped Camaro and it fits the hole in the floor fine. You might want to get that one even if you don't have a console.

Very late Muncies had a bigger output shaft with 32 splines and a fine spline input shaft. You would have to change your clutch disc and trans yoke if you have one of those.

I just did a Saginaw to Muncie conversion on my '69 with little trouble. I used the original Hurst shifter, however I did have to replace all the shifter rods, including the reverse lockout rod. The pivot for the reverse lockout rod also differs from the saginaw and needs to be replaced for the muncie. Other than that, it wasn't too much trouble, I did not need to replace the clutch or anything. Hope that helps.
