Lots of people do that but Shelby American will NOT install shoulder harnesses in that manner. The result is for most people that the attach point is below the shoulder, so in the case of an accident, the shoulder harness will push you downwards compressing your spine. The correct place to attach the harness is on the cross bar above your shoulders. If you don't have a passenger roll bar you're better off without the harness since in that case, you will be held upright and then become the roll bar.

But it's up to you.
