    i'm from germany and i will put a 6 speed behind a big block in my Skylark.
    I need to know which diameter the 26 spline input shaft has.
    I also need to know, how long the input shaft is and how many space is between bell housing and end of input shaft in mm or inches.
    The third thing i need to know, is where the shifter sits. I will have the original look, so please tell me the space between bell housing an shifter location.
    Hope anyone can understand my bad english.
    Thanks !!

    Search Under "Tremec TR 6060 6 speed transmission dimensions" or contact Tremec here:http://tremec.com/contacto.php

    The position of the shifter for the Tremec in the drive tunnel depends on the donor car application. The standard hanging pendulum shifter design can also be modified to change the shifter location in the drive tunnel.

    M20, M21 and M22s are Muncie 4 speed transmissions. Muncie's are much smaller than the 6 speed Tremec. I do not think you can install TR 6060 one in a Buick Skylark A body without cutting and enlarging the drive tunnel. It is going to sit higher in the car so you might consider the 2013-14 Ford Shelby GT 500 Shifter set up. The shifter is short. I would avoid the earlier year Shelby set ups because of a design flaw that causes gear grinding and 2nd gear lock out at higher rpms.

    Thanks for your help!, but i don't use a Tremec tranny. It is a ZF GS6-53DZ, it sits originally in a BMW 530D and can handle over 1000 NM and you can get one for around 500 here in germany.
    i must fab everything for myself, but thats not the problem.
    Can anyone help me now?

    Best Regards

    Thanks! that helps! the only thing i must know now, is how many inches from bell housing to shifter linkage.
    Has anyone a Muncie in his shop to tell me that?

    Best Regards

    You need the measurement from the front of the Muncie trans case to the center of the linkage base into which the lever inserts?

    Front of the bell housing to center of the linkage base.

    I'd be happy to measure my M20, but it has a Hurst shifter. Is there a feature on the case that you could use for reference?

    Your English is much better than my high school German from almost 30 years ago.

    Nice to hear FormerGNowner!

    I have to build the complete shifter linkage by myself and will have the original look from inside the car.
    I will also put the original Hurst shifter on top of it. I think part number 5335?
    So when you can measure your muncie including bell housing to the center of the linkage base (where the shifter screwed to the linkage).
    That would be nice!
    When i know that i can start building the linkage and can order the 4 speed hump.
    Which carpets are the best fit and color match?

    Thanks a lot guys!
    Best Regards!

    I know this is not a Muncie, but it's a picture that I could get my hands on quickly. From the bellhousing to the anchor bolts for the shifter (where it rises vertically through the floor) is 17.0" on the M20. My tape measure doesn't speak metric very well, but let's call it 43.2 cm.

    Can't open the picture.
    I will look today at my gearbox and will begin to build the linkage.
    Hope to get my big block finished this year, to put the car back together with lots of more power!
    Best Regards
