    3 speed to 4 speed conversion
    « on: February 07, 2008 - 09:33:23 PM »
    Changing out my factory 3 speed manual for a A-833 4 speed.  I know the output from the 3 speed is different than the 4 speed.  I have heard that I can either get a complete drive shaft out of a 4 speed car or a 727 auto car or just the front section of the driveshaft.  Is this correct?

    thanks

    thew slip yolk from a 727 or a 833 can be used , then you need to match up U joint sizes , the small 7260 is 2 1/8" inside the ears , the larger 7290 is 2 5/8", not sure if the length needs to change but I doubt it
