I converted the 69 to power brakes today, still drum drum. Used a 1/2 ton booster I bought off the parts board.
Parts list: booster & bracket+pushrod, new pushrod boot, vacuum T fitting, 2 ft vacuum hose, booster vacuum check valve if needed.

As it was


The old vacuum connection for the trans, need to install T fitting to hook booster to.


New fitting installed


Have to disconnect push rod under dash for m/c


I removed the pedal stop plate under the dash for working room. The bolt will hit the column, remove the master cyl nuts first so you can push the pedal way down for clearance.


Master cylinder unbolted and moved out of way


Booster bolted to firewall with master cyl, don't forget to get a pushrod boot for power brakes, it's different. Hook the pedal up first, before bolting the unit in, so you can have the pedal down to put the pivot bolt in.


Together inside with new pedal pad


Hooked up outside with vacuum line to new fitting.


Oh yeah, don't forget to adjust the brakelight switch because th e pedal will be slightly lower.
