Bore Size of Girling P10034 Wheel Cylinder

[Rally Pack 2000]

These specs use to be readily available online but its like my search engine has suddenly dumbed down and you simply cant get detailed specs on parts anymore just a sales menu of what cars it may fit.

Anyone able to tell me what the bore size of a Girling P10034 rear wheel brake cylinder?

 

Thanks

Ahhhhh that pretty big then I didnt realize they even came out that size!

My other option is Lockheed LW39171

Thats strange cause they specifically show 1300 Escort on the box of those and Escorts didnt have that bit rear wheel cylinders. The bigger braked cars had 19.05 while the smaller ones 17.85?
