Apparently, the third batch of Gripens (Gripen C/D) were produced with a redesigned radar section that featured enlarged radar back-end LRU bays, reflecting the NORA studies. Should be one of the reasons why Sweden scrapped so many Gripens by 2014 (should be more by now). Though this makes me wonder if the 66 Gripen As converted into C model also features a modified radar LRU compartment.
