My dragster uses a coupler, so I'm not at all helpful selecting a manufacture of which 1350 U-joint to choose. From what I've heard, for racing only, you do not want the greasable 1350 u-joint (weaker and more prone to failing), you want the solid U-joint which is what you are selecting.
The only other comment is I know they have steel driveshafts, aluminum driveshafts, and carbon fiber which is the lightest, and most expensive. Lighter is faster. If you had a new driveshaft made, verify the U-joints are phased to each other correctly.
