I'm changing out my kingpins at the moment and am taking the front disc route with my '51. I considered just ordering the bracket kit from cpp or classic parts.com, but taking the piecemeal route with my local auto store seems to only save me about $30 including shipping and I'm not sure I included everything that comes with the kit. No doubt I could save more by hitting salvage yards, but brakes are the last thing I would even dare to think about skimping on; let alone getting stuff from mid '70s vehicles. I just bit the bullet and 5 minutes ago purchased a kit on sale with performance online through their ebay store for $279, reg. $349. It seems to be the exact one from cpp, so except for minor mods, it should be a basic bolt on.
