Brakes are from 1970 mustang. I don't know the manufacturer of the brake booster, you can check with https://www.classicdiscbrakes.com/55-66-Ford-Thunderbird-Disc-Brake-Conversions
power steering
I'm currently considering an upgrade to my 56 power steering. Rebuilding the current is about $700 in parts and the upgrade is $1000.
Has anyone tried this?
