I have the ABS Power Brake electric power brake kit for sale. I used this on my '64. This is the 10-56 kit sold by them for $1300 new. I have the complete setup plus an extra pump brand new. I will sell it all for $800, including the extra pump! That's over half off and it's good as new!
One pump uses a distribution block (included) so that the accumulator can be mounted away from the pump if desired. The other (new) pump has a direct port for the accumulator to thread into, eliminating the dist. block and the short hard line. I wanted to package mine differently, so I got the second pump with remote accumulator.
If you have wanted power brakes with normal 9" booster feel but don't have the room, or don't have enough vacuum, or simply don't want the booster displaying so prominently in your engine bay, then this setup can solve that! Hide the pump and accumulator anywhere below the level of the master cylinder, even under the car completely out of the engine bay if desired!
