Most go with the new axle and larger drum setups these days.
Way back, a lot of folks had their SBC axles plugged and redrilled to 4-1/2" BC. As you can see here, the redrilled 1/2"-20 R holes get close to the edge of the stock flange. The redrilled holes need to be perfect on the locations or you'll likely have issues.......
You'd also need to redrill the drums. The hole location is not quite as critical as the axles as the register will locate it.........
FWIW, Moser sells stock length BBC axles for the 10" X 1-3/4" drum set up. A thicker flange compared to the stocker.........
