What is the best Fluid to use Standard or Synthetic i have a new dual master Cyl (not yet bench bled) new brake lines & front disks. So the only original parts are the rear cyl and lines on the rear axle
Unless you are planning some really hard driving (autocross) I would stick with conventional brake fluid that is readily avaliable at most gas stations or parts stores. I really don't see the need for anything fancy. The brake fluid now is probably better than what you could get in 1963 anyhow. Just my two cents...
