The nominal bb for the 105 was 113 or 107 depending on the year and gave you a 46 outer or 41 inner chainline. You'll need to take about 4mm off a side or get a bb that's about 8 mm shorter then the nominal.
This is Africa, 1943. War spits out its violence overhead and the sandy graveyard swallows it up. Her name is King Nine, B-25, medium bomber, Twelfth Air Force. On a hot, still morning she took off from Tunisia to bomb the southern tip of Italy. An errant piece of flak tore a hole in a wing tank and, like a wounded bird, this is where she landed, not to return on this day, or any other day.
