converting pedals from manual to automatic?

[Dakota Boy]

I have not done this swap, but I can say that the mounting bracket attached to the underside of the frame is welded in place. There is a big difference in the brackets and would suggest going with a power brake set up.

what piece is welded in place?

Update

Dual pedal manual clutch/Kelsey-Hayes power brake setup has been successfully replaced with a single pedal unit (non-Kelsey/Hayes).

No issues, other than having to make a brass spacer (because the eccentric bolt for adjusting the free play in the pedal was a smaller diameter than the hole in my master cylinder pushrod).

It is not necessary to bleed brakes when replacing pressure switch

Good job! I did this swap with my '59 Galaxie. While I had the brake pedal support out, I installed a microswitch on the pedal for my brake lights. That free'd up two wires going through my firewall for the old pressure switch.

Now, the microswitch turns a relay coil on, and the contacts pass all the current for the bulbs. It works as soon as the pedal is touched, just like modern cars. CLICK HERE for the site.

My Galaxie's brake pedal support is simply bolted to the firewall and dashboard. The steering column is bolted to it, too. Nothing is welded because that would complicate the assembly line process. Assemblers look at a ROT sheet, pick the correct brake pedal support, and install the studs through the firewall as another worker nuts the M/C (or booster bracket) under the hood.
