Seat belt kit from Motorsport Auto - Left vs. Right Side the same?

I bought this pair of replacement seat belts at Motorsport Auto today. They are made by Retro Belt. The hardware for both sides is identical, yet the installation is definitely not the same on the left and right side. It seems like the hardware is set up for the passenger side. A couple of mounting mounting brackets have a bend in them, and they are both bent the wrong way for the driver's side.

There are no instructions for mounting these belts in a 240Z ,by the way. There is a one-page instruction on some extra work needed to mount them in a '70-'71 (extra hole needs to be drilled in the car), but nothing else. That made the job much more difficult than it needed to be.

Has anybody installed these belts and did they have the same issue? I'll call and ask the folks at MA when I have a chance.
