What u joints do you guys recommend?

[my1stgn]

Im running a t-brake, and I will be upgrading the open diff to a Eaton Posi unit, 30 spline axles and c-clip elim. What u joints should I run? I was looking at getting the Dana Spicer solid 1350 u joints. Will these work? Also wanted to get yolk and whatever else I could/should upgrade before I go to the track. Driveshaft is stock and trans is a 200r4 with stock 8.5" 10 bolt diff. thanks for any help!
