Bob, sorry to hear about your dog, Fred. I know how special the bond can be, between man and animal.
On the breather lights, I say go with the bezels. Yes, they are larger then they should be, but I think the inaccuracies of scale will not really be detracting from the model. The cool factor will win over the scale nit-pickers.
I'd also lob off one of the breather lights, so that the length of the light bar matches the breather length. Another little sacrifice, I know, but I would much rather have things looking good.
I like that you decided to mock-up the breather light bars like that. Something I wanted to do myself, to check how it would look on my own trucks. You've saved me some of the work!
