    here is what ck-5 page talks about: </font><blockquote><font class="small">In reply to:</font><hr />
    The 14-bolt (FF) uses a 1350 series u-joint and will not match up to the 1310 series u-joint that the 10-bolt driveshaft uses, so a trick u-joint (1310 on one side with 1350 on the other) will have to be used to accommodate the two different sizes which can be purchased from a parts store or driveshaft shop

    [/ QUOTE ] but i cannot find a part number or a parts person that can find it. i keep getting solt the perfect side for the 1350 side, but the wrong side for the 1310 part. anyone know a napa number?

    I have a 77'gmc jimmy, had 12 bolt, now sitting on a pre-'78 14FF /forums/images/icons/wink.gif

    I use a Napa part # 348 (conversion joint). This is the u-joint I needed going from a 12B to a 14FF, it uses the outside lock rings on the drive shaft.

    if the 348 doesnt work, try the 447

    mj - thanks for the spicer part # .. i didnt know that they made one, makes sense that they do though.
