Hi, I have a water pump stamped 12H3255 on my 1974 MGB GT that I need to replace. The 12H3255 is about 80 mm long between the base and the front of the pulley plate: https://www2.mgcontact.eu/pictures/albums/userpics/normal_IMG-3620.jpg Could anybody tell me this measurement on the following pumps ?...
