Did they sent me the wrong axle?

So i snapped a front CV axle a couple weeks ago. Finally got around to replacing it. The guy I bought it from said he replaced the front axles with sixity axles and after some good reviews I just ordered a replacement from them. They look drastically different though so just wondering if anybody can shed some light. The inner cup is the main concern as the new on is a lot shorter and flared more on the end. Anybody have any ideas or should I just trust them and try to install em. Seller prob didn’t change em out to be honest.

Also, after spending a couple hours trying to get the old one out, I finally went out and bought some Nano ProMT penetration oil. Let it soak overnight (and without much expectations) but two yanks this morning and slid right now lol
