RV2 AC compressor Rebuild help

It looks like the bore is 2-5/16. The distance from the piston to deck at BDC looks like it's 1-5/16", and going by my calibrated eyeball it appears the distance from the piston to deck at TDC is about 1/16". That would give a stroke of 1-1/4". Do those figures sound accurate? Assuming those measurements are accurate, that makes the displacement π(2.312÷2)²×1.250×2 = 10.495549536 = 10.5 cubic inches after being rounded up slightly. That makes it comparable to the York 210, which is 10.3 cu-in.
