Replacement casement window hinges needed

Greetings!

I am in need of replacement casement window hinges; I believe the type I have is called a "2 bar set". In configuration, they look nearly identical to the hinges depicted in your Swisco Youtube video at "https://www.youtube.com/watch?v=Qm8bUJO2eaM"
As close as I can measure without having yet removed the hardware (which if possible I would prefer to do only once, at time of replacement), measurements appear to be:

10" (The stationary rail that mounts in the window frame, and is depicted as segment "L" in the Truth Hardware drawing, attached)

7.5" (the length of the bar that mounts on the window itself, and has the black plastic [?nylon] sliding shoe that slides in the track of the stationary rail)

Approx 5.5", maybe 5.25" (the hinge arm, the "hypotenuse" [angled piece] connecting the two parts above, riveted on one end to 7.5" piece above)

Approximately 5.5",maybe 5.25" (depicted as segment "A" in the Truth Hardware drawing, attached)

Do these measurements need to be exact (?), in which case I will remove the hinges and remeasure, or are the measurements above, plus the attached photos, close enough for you to recommend a specific set that will work with my window? The replacement is needed because the plastic shoe is failing.

In case it is pertinent, my window hinges are "FCR" (Right-sided, as seen from the curb). The attached photos were taken of the top of the window only, while on a ladder. I can take others, if needed.

Thanks!
