Hello,I am diying a 8x10 camera but the specs of film holder on google make me confused.According to the specs below,exposure height+distance to the exposure field is 10.026"+0.775"=10.801".The retaining tab location is 10.85,so the gap between tab to exposure field is only 0.049" left?Any one can explain it for me?Thanks very much.

If a list of standard dimensions does not include tolerances, then you know it’s not a good reference.

I'm confused.
Retaining tab? I've always heard them referred to as the locking ridges
The retaining tabs being the metal "L" that holds the dark slide in place.
