72 Demon Power Steering Gearbox/Coupler Help...?

Mine is power steering. That's why if you do go with the U-joint setup Its best to call the company you're getting it from and make sure you're getting the right one. I don't remember the spline count and not all the steering shafts are the same as well. I wound up sending pictures of what I had to Flaming River and got the right coupler the first time.

Thanks doosterfy!
