Need help! Stepside cross rail correct location.

[Smokeem]

Guys need your help in a big way. I have inherited a 72 Chevy Stepside that my late father in law was in the middle of building. I'm working on getting a rear fuel tank put in. Currently the bed is 3 hours away so I'm not able to mock everything up with the bed on, to make sure I don't have clearance issues later. My question is in the attached picture does the rear cross rail look to be in the correct position?

Thanks Rick
