Distance between engine cradle and frame

Does anyone have the actual measurements for the distance between the engine cradle on the swing arm to the frame rails. I know they are different but mine appears to be a little excessive but I don't know what it should be. The left side is about .5 inches narrower than the right. Thx Drummer99

I don't think there is any actual quoted dimension for this. The standard head steady is built offset by 1/8", but the difference in the dimension between the cradle and frame is normally about 3/8" (so in that situation the cradle would be offset to the left of frame centre by 3/16").
