    Long story made short --- I got a NEW 1 ton driveshaft from a online driveshaft company (I won't name them yet). They sent me a shaft with an end that is the wrong size
    for the yolk I have. It uses 1410 Ubolts which are 4.25" wide. I need the 1310 (which I think is the 3/4 - 1 ton ujoint and they are 3 9/16" or 3 5/8" wide). Is there a NAPA U Joint that has the 1310 and 1410 ends??? I had a NAPA 447 when I still had my 1/2 ton shaft and it fit perfectly.

    If not, I need to send this damn thing back (for the second time) to get it rewelded with the correct size ears. Please help fast......my K5 us stranded until I can fix this!

    <font color="blue">What end of the driveshaft is this? If its the axle end, just put a 1410 yoke on your 14 bolt

    that is a HUGE difference in size.
    the 1310 is about the smallest ujoint used in a fullsize.
    1410 I dont think was used by Chev.

    3-5/8" cross should make it a 1330 or 1350. 1310's are only 3-1/4" across.

    The 1350 (3-5/8" cross x 1-3/16 cup) yoke is the most common on a 14FF.

    There should be a bastard joint for 1350/1410.

    1330 &gt;-&gt; 1350 = 5-648X
    1310 &gt;-&gt; 1350 = 5-460X
    1310 &gt;-&gt; 1330 = 5-134X
