Swap from 10 bolt to 14 bolt semi float

[02turbogixxer]

I have a 96 2wd Chevy truck and I am going to pick up a 14 bolt Semi Floater today but I have a question. Is the U-joint on the Semi Floater a 1310 or 1350? I know the 14ff is 1350 but I have searched and searched and can't find any info about the U-joints on a Semi Floater.

Also I am pretty sure I'm going to need new U-bolts for the springs too right?

1350 u-joint. You will need different u-bolts.

You'll need different spring plates to acomodate the bigger u-bolts.

Thanks for the help guys.

I think the yoke on the diff depends on what the axle came in... My 14SF came out of a 97 Z71 half ton and had the same yoke and u-joint as my '88 blazer (where the 14SF went). I got to return the conversion u-joint that I had bought.
