M20F Weight and Balance Issue

[crxcte]

I had an avionics shop install some garmin radios and got the following weight and balance report.  I know the moment was put in the arm at the top which created the new enormous moment.  My question is the arm on the radios, all radios came out of the stock panel, shouldn't the arm be the same for all?  The shop had 16 and 20 inches, since there on the same panel shouldn't it all be the same arm?

I asked the same question with my avionics. What they told me is that the arm is different because they go by the center of the readio installed. Longer Radios, less arm. Your wight and balance numbers are very close to the W&B for my 69F also.  I think that you are good.   Enjoy that 430, it is a dream.
