14 bolt sf swap need help with u joint!!

Most gm shafts for half tons use a s44, are you sure its a 1330? If it has internal snap rings, its an s44 joint. 1330's use outer snap rings, and have the same dimensions as a 1350 except for smaller diameter caps(it uses 1310 caps, but the larger axial portion of a 1350).

Got my u joint today and its the wrong one. Cap sizes are right but wrong width. Anyone able to help?? Part number I got is p448
 
How is the width wrong? Is it correct at the axle side but not the shaft side? Are you sure you had a 1330 and not a 1310?
 
Axle side was correct driveshaft side is too short. The 448 is supposed to be the right part according to another post on this site.

The 448 IS for a 1330 to a 1350. So you either got a misboxxed joint, or you ordered the wrong part. Need to know actual dimensions of what you need to tell you anymore. Otherwise were shooting in the dark for what you need.
 
I need a 1330 to 1350.
1 and 1/16 on the one axis.
1 and 3/16 on the other
3 and 5/8 from cap to cap.

The one they gave me was in a box for a 448. 1 and 3/16 on the one axis and 3 and 5/8 cap to cap. The other axis is 1and 1/16 cap and 3 and 1/4 from cap to cap

That is a PRECISON 448 or NEAPCO 2-3050. You said you already got a 448 which IS what your asking for. The dimensions you give of the joint you got are for a 1310 to 1350 which is a 348 joint, not a 448.

So they put a 348 in a 448 box? Im kinda lost lol. The measurements for the 448 i have are the right size caps but it's too short on the one axis.
 
It seems as though you got a 348 in a 448 box. I looked up the specs you gave, and it is for a 348. The 448 IS what you say you need.
 
And that's what I had thought too because I looked up the specs for the 448 on several sights and none of them matched what they gave me.
