Hey Kevin, the mounting bracket of the Dexter Self-Contained Hydraulic Jack # DX72CR that you referenced has mounting holes that are vertically separated by 2 inches so it would attach to that crossmember you have based on the dimensions you listed.

Do not know the mounting distance between the mounting plates on the jack. You said it was holes every 2 in which can't be possible. There Is two mounting plates on the jack nothing in the middle. My holes are - top to bottom 8" center point. Side to side 4.5" center point. I want to know will this jack work?

@Kevin Try this link to see the dimensional drawing for the jack. You can see the distance between the mounting holes. I think maybe we were talking about two different things as the distance between the mounting plates is 12 inches. https://images.etrailer.com/static/images/image/expert/0/e/c/0ec72ea716044dbb9cc66167575047ac_0/0ec72ea716044dbb9cc66167575047ac_0_800.jpg
