Witch slip yoke would I need for my 4l80e swap on a 2000 GMC Sierra rcsb .The output shaft has a threaded hole in the center so would I need the spicer 2060108 or would I be fine with the spicer 3-3-5571X. And would the 447 moog or precision u joint fit my stock driveshaft?

 

What size up joints are on your drive shaft?

 

Its either a 3r or 1350 . Do U know how to tell exactly ?

 

Since I had 1330 joints on my DS I went with this one

Dennys Drive shafts has a wide range to choose from. I'm sure they can help.
