    Is the 1350 or the 447 the only Ujoints that will fit the 14B FF rear end?????

    I was told, and I think it was a bunch of BS, that the 14B uses three different UJoints - INCLUDING the 1410???

    Am I correct? Any GM techs out there????

    Thanks
    Chris

    I, too, have only heard of the 1350. And, IF there are others out there....the 1350 is much more common.
    And the reason the 447 fits is because the two ends that go on the yoke are 1350 caps...the other two ends are 1310 (I think that's the u-joint number for the conversion joint).
    I'm interested to hear if there are larger yokes out there.

    I don't know what the application is but Dana actually makes a 1410 yoke for it. I can post the part number tonight if anyone wants it.

    I looked at it again.....what I really need is a 1410 for the driveshaft connection and 1350!!!! for the differential connection.

    I am beginning to doubt what I need exists but I am still praying!!!

    Any ideas???

    as was previously stated...
    you can change the yoke to match the big shaft.
    it is a better option then finding oddball ujoints IMO
    why use special order parts for a wearing item?

    I understand that there may be easier routes -- last resort is to change the driveshaft to 1350 ujoint mounts. BUT......

    I'd much prefer to use a 1410 to 1350 conversion Ujoint ---- So, I just need to know IF IT EXISTS!!!!


    Thanks for any additional help.
