did the 1968 Mustang Fastback come with power brakes? thanks, Justin

 

I believe it was an option.

 

Yup, option.

 

Few early Mustangs came with disc brakes and even fewer with power assist, but here's a link to how I installed a 2.3L Fox Mustang brake booster & later, changed to a 5.0L Fox Mustang brake booster in my '68 Mustang:

Here's a photo of a 2.3L Fox Mustang brake booster with an SN-94 4-wheel disc master cylinder I installed in a '65 fastback:
