Hello,
New here and to the Riviera world...
I am helping the owner of a 1983 Convertible with some issues he has and getting his car back on the road...
I am looking for a master cylinder for the car and have had no luck with local and online vendors finding the correct listing for a replacement unit.
The car is an 83 convertible with a V6 motor... it has 4 wheel disc brakes and the listing for the master are very confusing and sometimes wrong. So I do not feel comfortable in pulling the trigger with an online vendor...
The current set up is a booster with an aluminum body with a plastic reservoir..
The part number from GM was 18030428 and is discontinued.
My research has shown a cast iron unit and I believe that was used with a Hydr boost set up.... most of the others state rear drum brakes..
Any help or direct with this would be greatly appreciated ... Thank you
