Can't help you on manufacture but in case you didn't know, the bearing assembly needs to jive with your pressure plate choice. Diaphragm, Borg and Beck[ what our cars came with] and Long[ what Ford used] all take different overall length units. The Long style does not work with stock flywheels so most likely you don't have that but some aftermarket wheels can come drilled for it. The other two have the same bolt pattern. Whose cloth unit are you using? Maybe source from them?
