(2) "center sump" 360 pass car pans to choose from: the 392 and the 876. both sumps are ~8" long and on the 392 the sump starts ~4" back from the front lip and the 876 it starts ~2" back (this is from a plumb line vertical down from the front lip) and the 392 pan is what you need for an early A body and they use different pickups. EDIT I forget which of the 2 pickups (top/middle) are correct for the 392 pan
