Is it possible Paul, and Paul that you each are talking
about two different pads? Perhaps the Mintex pads that Moss
USA distributes are different than the MGB V8 pads that the
MGOC has?
The Moss USA catalog does call the Mintex pads "U.K. spec.
MGB-GT V8 pads [that will] fit stock calipers", presumably
the 4 cylinder car stock calipers.
