Two different upper ball joints from O'Reilly?

[c10boob]

Several months ago I purchased and installed a Master Pro upper ball joint from O'Reillys for my '71 C10. It looked SIMILAR to this:

I then put my project on hold until winter was over, and today purchased a Master Pro upper ball joint from O'Reillys for the other side of the truck, and this one looks like this:

It seems much sturdier and appears higher quality. The hardware is better and the rubber boot is larger. The first one I bought fits fine, and I'm 99% sure the one I bought today is correct because it looks like all the photos online that I find when I search for C10 upper ball joints.

Anyone else experienced this?
