Just get a master for a 69 C body with drums.I have one on my kids 62 300 and its been perfect for 10 years.You do have to plumb it in for the extra line.I got some brass blocks in the junk yard off of older mopars with drum brakes so I didnt have to try and find any parts.Just remember if you need to check rear brakes you need a special puller to get the drums off.That and the frts have dual wheel cyls.Also get a good 7/16s 6 point socket to adjust them.Rocky
