Problem with Nord Maroc projection

I have a problem with Geotiffs in Nord Maroc projection, the geotiffs were generated using TNTMips and projected to Nord Maroc but they are importing into ArcGIS 10.7.1 about 400 km to the south of where they should be. The parameters for the projection are exactly the same as the shapefile for the AOI. If I import a version of the image in WGS84 UTM29N and do a transformation the image lies in approximately the correct space wrt to the AOI. Any ideas?

Details of projection of AOI:

Projected Coordinate System:    Nord_Maroc
Projection:    Lambert_Conformal_Conic
False_Easting:    500000.00000000
False_Northing:    300000.00000000
Central_Meridian:    -6.00000000
Standard_Parallel_1:    37.00000000
Scale_Factor:    0.99962577
Latitude_Of_Origin:    37.00000000
Linear Unit:     Meter

Geographic Coordinate System:    GCS_Merchich
Datum:     D_Merchich
Prime Meridian:     Greenwich
Angular Unit:     Grad

I am using the same parameters for the image but it will not import into the correct location. Also tried transforming the WGS84 version into Nord Maroc using QGIS but when I import the resultant Geotiff into ArcGIS it again lies too far to the south.
