Bill,
?
I'm not sure whats going on. I noticed you have SN 0045, mine was a V2 radio also, SN 0042 so built at the same time yours was and my new V3 board just dropped in very easy. Maybe the heat ink is slightly bigger, IDK. Maybe someone from HFSignals can give some help here. A picture might help also.
