Thanks for the help @HaureN! I was able to find all the equivalent maps. Here is the list in case someone else comes looking for them.
pab_church = ac_en_hall.gat
pab_camp, 1@pab = 1@pdb
1@pab2 = 5@tower
1@pag, pab_dun01, pab_dun01c = gld2_ald
1@par, pab_dun02, pab_dun02c = gld2_gef
1@pau, pab_dun04, pab_dun04c = gld2_prt
1@pac, pab_dun03, pab_dun03c = gld2_pay
