    I went to Napa and asked for the 447 ujoint and they could not find it. Does anybody have some other part numbers for the 1/2 ton to 3/4 ton conversion ujoint. In other words to use the 1/2 ton driveshaft with a 14 bolt diff.

    Thanks.

    Nappy changed their part numbers. The 447 is now a 2400447. If they still can't find it, tell them to cross-reference a Neapco 2-1153.

    This is for a 10-bolt to 14-bolt. 12-bolt to 14-bolt is different. You said you have a 1/2-ton but didn't specify which axle.

    12-bolt is Neapco 3-3140 / Nappy 2400358 (it could be 2400348, though. The web site says 2400358 but the old number was 348, so it might be a typo)
