That'll need tweaking if the game allows it as the JP233 is a two part arrangement, the front part latches to the forward LDERU station on the shoulder pylon and the rear part to the middle HDERU station. Illustrated by the photo below, you can see the pair of forward MACE lugs at 14 inch separation to fit the LDERU and the rear MACE lugs at 30 inch separation to fit the HDERU. You'll have to forgive me, I'm an armourer and had the misfortune to help fit JP233 once to ZA354.
LDERU - Light Duty Ejector Release Unit
HDERU - Heavy Duty Ejector Release Unit
MACE - Minimum Area Crutchless Ejector (i.e. the ERU has no crutch arms (sway braces) sticking out to cause drag)
