As I said, they're sort of scattered...absolutely can`t find a link right now to Netherlands results by township, sorry.
Only thing I find is by province...which does not to any extent give an idea of the SGP vote`s concentration.
Drenthe CU 2.9, SGP 0.3
Flevoland CU 3.6, SGP 2.1
Friesland CU 3.2, SGP 0.4
Gelderland CU 2.5, SGP 3.0
Groningen CU 4.4, SGP 0.3
Limburg CU 0.3, SGP 0.1
Noord-Brabant CU 0.6, SGP 0.4
Noord-Holland CU 1.0, SGP 0.2
Overijssel CU 4.4, SGP 2.2
Utrecht CU 3.1, SGP 2.0
Zeeland CU 2.9, SGP 7.7
Zuid-Holland CU 2.2, SGP 2.6
The bible belt goes from the whole province of Zeeland in the southwest (Reimerswaal municipality SGP 30% for example), and the rural areas of the south of South Holland province through Utrecht province and the west of Gelderland province ("Betuwe" and "Veluwe" regions) to the west of Overijssel province (Rijssen-Holten and Staphorst municipalities for example). The most extreme one is Urk by the way, in Flevoland. 92% NO yesterday. Normally CDA, SGP and CU all score about 33% of the vote, and the PvdA and VVD sharing the 1% remaining. :-)
Yesterday massive NO-votes were seen in the bible belt, the socialist/communist area in the east of Groningen province and the area around Rotterdam, were the LPF party was huge in 2002. A majority of YES-votes (~50-55% YES) were seen only in the richest municipalities, where the VVD is strong.
