I spent 6 years as an armourer on Hawk at 2TWU. The LAU-7/A needed a form of adaptor with suspension lugs to mate with the 119 ERU in the pylon, which was also used to carry CBLS when required.
Remembering how tight it was to change the Nitrogen Receiver bottle in the launcher (there was just enough clearance to withdraw the bottle with the flaps down when the jet was shut-down), I suspect flap clearance would have been part of the equation also.
