Used TKO600 ?

[AM.MSCL]

I am looking at finally pulling the M-21 Muncie out of my 69 Firebird and install a TKO600 in it behind the 400 engine.
I have seen a few used TKO600s show up for sale and have been trying to find out what else is going to be needed.
I know that I am going to need a new crossmember, trans mount and driveshaft (or shorten my current one).
I am pretty sure that I will need a different clutch do to the spline count?
What about
flywheel?
pressure plate?
Bell Housing?
I have a center console so offset shifter?
I also have a VSS for my speedo gauge.
Thanks

Flywheel is the same, bellhousing depending on what version trans, and preference of safety bell or not.

Some m-22 and m-20 had 26 spline, the bell housing for a GM TKO 600 is the same mounting for a Muncie

Hurst makes shifters also

If it comes with the bellhousing it will bolt right up, although IIRC, the TKO has the same bolt pattern as Muncies, so it should bolt up to a Muncie bellhousing. GM TKO's have a 26 spline input shaft, I don't know Muncies, so I don't know their input shaft spline count. Keisler makes an offset shifter for it that supposedly centers the shifter perfectly. I don't know, my car doesn't have a center console so I just got the standard shifter. I'm pretty sure it uses a standard tranny mount for TH350s/TH400s since that's what it looks like, but hopefully someone can confirm that. It also has hookups for mechanical speedometers and electric speedometers.

Hope that helps.
