I need a couple replacements...Will it be as simple as measuring the following pic to find the right crank? Or can you tell by looking at it? Thank you!

I'm not 100% sure what you have just by looking at it, but the style seems close to what Truth makes for their operators. Assuming I'm right, that means the diameter of the handle's hole should be 11/32". You should remove your handle and confirm. That's the only way to be 100% sure. The diameter of the hole is the most important measurement.
