With the right puzzling together, you should be able to fit the MA, RA &
Snugride 
I had my
FF Boulevard in the center between
RF Wizard (driver side) &
Snugride -- I also had the
FF Boulevard center between
RF Wizard &
Parkway.... The
Parkway wasn't used that often, or I'd have had it in the center: least protected child at farthest point from impact.
