1987 v10 rear u joints

[cerial]

My 31 year old beast with like 104k is still rocking it's stock u joints with the plastic stuff inside.

So when I torch these things to have the goo squirt out and hammer on the inside of the cap to pop off the caps out of the yoke I replace them with u joints that have outer clips right?

There is a ridge hiding in there for outer clips?

Thing is just a driver and mostly stock doing the joints as preventive maintenance before the snow flies. Doing the brakes next month and then doing the floors before it gets to cold then done for the year.

I want everything laid out to make this hour job a hour job. I am tempted to get outer clips and inner clips then just return the inner if they turn out to not be needed. But think there is a ridge in there for outer clips.

What are you guys using for u joints?
