Hello all, as some of you may know. I need a new master cylinder for my 1963 Mercedes 220Sb w/ single circuit, disk brakes. Does anybody know of a reliable source that sells them for cheap or a rebuild kit. The reason I ask is, I don't want to waste almost 500$ on the Classic Center master cyl. The part number on pelican parts was 001-430-63-01-MBZ. Also I don't want to buy a brand new master that was sitting for 20 years on the shelf. If anyone knows a cheap rebuild kit I'd appreciate it. Thanks!
