Here is what the 3 wood bows look like on the iron set for the Model T roadster (runabout)

And since you have shortened the T stanchions and using Model A top irons, you will just have to be creative. The Model T front bow is placed in front of the windshield, hangs over the windshield. No sure what 'loops' description you note, but the circular boss on the stanchion is for the knuckle for the tilting windshield, a '26-'27 has both frames that tilt. Your will have only the lower frame.

And the little 'eyelet' is a Lift the Dot male fastener, those on the stanchions for mounting the removable side curtains.
