The only problem that may rear its ugly head is the hook not being adjustable.
I debated in my mind about the adjustable top hook, but then I decided that I truly wanted snatch and go and you cannot do that if you have to adjust the tophook. I also considered the flip over style top link connector, but in the end I decided that, "No I am making the Standard for me and everything WILL conform to this standard."

I am now in the process of conforming everything. I guess the manufacturer did not have the standard in mind when the implements were built.

(The fingers all are pointing at me!!!!!) Oh well I have an excuse to spend some shop time.

I need to put a wood stove in there though it is getting cold.
I have the RB conformed, and the scoop, and the trailer hitch, and I am working on the rollover. When I made the implements, since the arms were adjustable, I did not work too hard at fitting the Standard for CAT 1. If it was close it was good enough. But now I need tighter tolerances and have had to modify a 1/2 inch here and a 1/4 inch there.
With the rollover, I had a "tent" toplink tower, but since I had to modify it (1 1/2 inches too tall), I decided to make a new toplink which is more "Gannon-like" as that better fits my imitation Gannon.
Tomorrow, I will try to get to the Rollover and then will post come pics.
