Cool! I have a '76 M-bird strung B E A D as well. I think it plays better strung with a B than E A D G. PLus, with the 24 frets Ive got all the high notes Ill ever need.
That holds for my cheap 34" Ibby GSR200EX as well. I converted it to BEAD. The B, a .130 Ernie Ball flatwound, is rock stable and produces a well defined sound. It also intonates perfectly. I'm happy I got rid of the G-string, as it had dead spots and sounded very thin.
