I suspect you're speaking about the rdtrans2008 or rdtrans2018 grids that are for 
transformations between the Amersfoort datum and ETRS89. I can't see any grids between 
Amersfoort and WGS84 registered in EPSG, because of the time-dependent nature of WGS84 
(well you could use the grids for transformation to WGS84 if you're ready to consider ETRS89 
== WGS84 for your purposes).
