U Joint Surprise

[MACO]

For the most part my truck has not been messed with and is mostly original. My u joints are leaking grease so it is time to replace them. I went to take a look and verify the sizes (looks like I need a 1310 and two 1350) and was surprised with what I saw on the front u joint. A PO had used a chisel to "stake" the u joint clips as they did not fit into the groves. With a small screw driver I was able to easily pop the clip. I am not sure how long it has been like this but I am surprised the clips did not come out at some point. I was going to go for some BBQ with my daughter this weekend but don't feel comfortable with the clips(even though I have driven many miles and not know the clips were installed like this).
