I thought that I posted this earlier but apparently not. I want to install an AF Meter in my Model A. This would be a permanent install, not just for testing/tuning exclusively. I tent to go with middle of the road in the price vs quality department. If there is a good quality meter available in the 2 1/16” range but if not available I can live with a larger meter. I’m looking for some advice re what to buy, I know very little about this subject. Thanks
