Default Disc brake conversion for big car

Since I often hear of people struggling to find discs for original disc cars or looking for a conversion kit this eBay listing may be a solution.

Don’t know the seller but I have bought from him often on eBay and always got exactly what was described. Never spoke by phone but often asked questions and had prompt answers from him. He says local pick up only but I imagine he’d ship if you only wanted brake components.

By the way, having recently added a factory disc brake set up to a 69 Catalina from another 69 I can comment on what you need;

…Booster, master, delay valve (booster is dual diaphragm, master is readily found, cardone has a very similar model, delay valve is same as GTO).
…brake lines between master and proportional valve (proportional valve and mounting bracket is same part number for disc or drum on big cars)
….brake line between left and right side (runs under engine crossmember, just different enough that you need it)
…frame brackets that hold the flex hose are the same as for drums but are mounted reverse
…rotors, calipers and splash shields (these are obvious!) but unlike A bodies the spindle is the same disc or drum.
…lastly are consumables like pads, flex hoses, seals etc
