Hydraulic bearing clearance issues and workarounds?

I have a ram hydraulic bearing setup which has different instructions than say american powertrain, I glossed over the instructions as I'd already watched videos on how to the measurement. Well since the Ram method is different my numbers were off, I still have to call them on Monday and ask if I can just measure from the diaphram fingers to the scattershield block saver since I already have the flywheel/clutch/pressure plate mounted and I don't want to remove it to measure from the crank flange to the block per this diagram.
