This guy ask this question back on Sept 8. I didn't answer him until the 15th. Your on this forum all the time .. Why didn't you help him? You are here to help , right G-man !!!!!
I went with all new parts because I don't do anything half ass. I ask him what his budget was. I was waiting to hear back from him but got you instead..
You might spend the money on a new pb6 & controller & still use the old solenoid, but I wouldn't. And as far as the motor goes , they have come a long way since 1973. I would think this guy wants to upgrade because of efficiency & power. He wont do it with just a pb6 & new controller.
