U joint. Internal vs external retention

Well I'm replacing u joints on my 1995 xj. I went to two different napas and got two different ones. They are both precision brand super strength. One is part number 280 and the other is 378. The 378 came with the normal c clips. When i opened the other one they looked weird. Kind of like a bubble letter c. I looked all around with a google search and couldn't find too much.

Now, here's where I get confused. I don't really know how the internal?(part number 280) clip goes on and works. I also don't know if each type is determined by the yoke, or f I can use either one.

If it matters I don't have abs, ( guy at napa asked don't know of it matters)

Sorry if I'm not clear on what I'm asking. Been searching for awhile and a little frustrated, I just want my u joints in!

Any help appreciated, here's some pics

internal c clips are for the axle shafts. external are for the drivshafts.

top pic is external, bottom pic is internal

internal go around the groove on the bottom of the cap. you will see when you dissasemble your current ujoints
