I am in the process of converting my 1969 mustang over to power disc brakes. I saw the post today about the difference between the 1969 and 1970 boosters and brake pedals. I have a 69 power brake pedal, but I have a 1970 booster which has the straight push rod, not the one with the curve for a 69. If I went to Autozone and bought a rebuilt 69 booster do they come with a push rod? Also is there and advantage to using either a Bendix or Midland style unit. Thanks for and advise you can offer.
