U-Joints

What is the best replacement U-joints for stock driveline on an 85 Olds 442. I need both Ujoints. I've tried searching but can't find a definite answer.

I took mine to the auto parts store, they put both in for me, wasn’t much. And you can grease them.

I gotcha. I’m going to install them just need to find right ones.
Looks like there two different sizes. Did the 8.5 rear ends and 2004r have the bigger u-joints?

Not that I'm aware of. I believe the yokes are interchangeable. The easiest way to determine what you have is to measure it. All that is needed is a cheap caliper from Harbor Freight.
