Brake cylinder type

[A_Rescue]

I own a 1971 monte 454SS.  Does anyone know the brake type used on this vehicle.  The book shows 4 versions, Delco Moraine Single or dual diaphragm, and Bendix single or dual diaphragm.  I am not able to look at the car today and I am hoping to get the parts on order....  or  a rebuild kit for the diaphragm and master cylinder

 

brakes idiot light on and brake fluid seeping on the diaphragm outer case from master cylinder

 

Thanks...  John

Hey John, I cant tell you for sure. My 71 parts car has the Delco as does my 72 for the booster, and all of my cars have the dual master also delco. Hopefully someone else will chime in with more info.
