Generic 500w spindle mount fit on gantry plates or extrusions?

Hey guys. This question is way different than my other one so I'm just making it its own thread. I already have one of these generic 500w motors. But I have no idea if it can mount on gantry plates or on the C beam themselves. I'm still trying to plan my upgrade so I need to make sure what I buy actually works haha. does anyone know if it fits? I did some googling and I just keep finding other 3018's and custom mounts. I feel like when I got it months ago and I was trying to figure out what its metal mount was for, I saw one bolted to a C beam. but I can't re find it so I'm not sure. I'm wondering if anyone here has ever mentioned using one. Thanks.
