LCA Cross shaft- Is this Moog?

[young grasshoppa]

I ordered Moog LCA cross shafts for my truck from Rock Auto. When I opened the the boxes I noticed that they had different finishes, and the shafts stopped at different points (where the end cap screws into). If you look at the picture you will notice that the darker one is similar to the originial (dirty), they are both the same length, and the dimple is in the same spot. I returned the lighter one the other day, and they sent me another however, it is the same (lighter). Should I have sent the darker one back? My concern is that the lighter one shaft is not the same as the original (larger gap next to end caps). Did one of the boxes have another brand part in it? I know there are some folks that are working on similar projects right now that may be able to chime in.
I'll show pics of the rebuild when it is all wrapped up. Thanks!
