Rag joint elimination???

I am hoping to replace my rag joint with some sort of U-joint setup. Whether it be flaming river or CCP or what have you.
I thought I was ready to buy parts, but I am confused and looking for some answers.
Everything I read says the replacement joint needs to be 3/4" 30 spline on the steering box end and a 1"DD on the shaft end.
OK, sounds simple enough,
Then I look at Steering box info and depending on where you read it says the steering box input shaft is a 26 spline.
What gives?
Is it because of the flat section on the input shaft and the u-joint is splined all the way around and not "keyed" like the input shaft? Or is there something I am just not getting?
Am I just overthinking this? EVERYONE seems to be unanimous on the the fact that the 3/4" 30 spline is the part to use, I just don't seem to understand how a 30 spline opening fits on a 26 spline shaft.
