Fumblin', there a brand new ones available for about $140.00. Not remans. I didn't see one in Napa online but it's a newer part with the last 18 months or so. The master is integral with the pedal mount to the tranny. If you had an AD, I'd say go for a Late '60's mustang dual res, but you don't. The re-engineering that needs to go into the swap may get to be as much or more (when you figure in a new tranny, motor, on and on.........) than just bolting a brand new master. With new lines, and a new master, how much driving are you going to do in the rain and salt.........should last you for as long as you own the truck, and then some. The original went for awhile. grin
