Stock weight distribution for various body styles - can you improve balance w/out drastic mods?

66 Barracuda 273 - 55.5% front, 44.5% rear
67 Barracuda 273 - 55% front, 45% rear
Other A bodies?
Not measured, from articles.

It’s surprising that the 67 would have better weight distribution. I always assumed that one benefit of that glorious rear glass on the ‘66 would be that it sits over the drive wheels.
