Hi guys:
It has been a while that I posted anything but now I am back on my old rig. I gona swap to front disk brake and also I am changing the front end. The only parts that I don't have is Booster and master cylinder. I was planning to use late 70 master cylinder but I see that they have two different ones; JB6 and JB7. What is the difference? which one should I use? also What is the difference between 7" and 11" booster? Just morre braking power? I appreciate the tips.
By the way, in changing the front end, any tips?
