Rear Brake Pressure Regulator

Gents, anyone help me out with a quick question regarding rear brake pressure regulator, basically has my 1991 Clipper got one or not? I'm overhauling the rear brakes and need to know whether to order one and replace it. Many thanks.

Afaik soft tops do not have the rear regulator that the tin tops have, they have a different type that is up near or actually on the master cylinder.

as above, look on the master cylinder you cant miss em if fitted big cylinder looking things inline with the rear pipes

Thanks guys will have a look
