    are there any alignment issues i need to be aware of? or if it fits, it fits?
    and what about the angle of the dangle? anything there?

    well your spring perch and spring packs will set the alignment butt you may need a degree shim to move the angle of your dangle?/forums/images/icons/smile.gif
    Not sure how different the 10 is compared to the 12, if any....??
    I know, no help right....
    Just slap it under there and go for a drive. If it vibrates then the angle is off, if it's smooth yer good to Go!!

    ok, the 12b is under the truck, but the yoke and driveline won't bolt up. i pulled the yoke out of the 10b, but it won't slide onto the 12b shaft.
    is there a yoke that will fit the older 12b, but match up to my newer 10b?

    man, i wanna drive this bad boy!/forums/images/icons/smile.gif

    Yeah Napa has them Me and a buddy did the samething when we swaped a 12 bolt in his 87 untill he could make a new shaft if you have both u-joints they can go off of that or if you know what year the 12b axel is that would work to .
