Fit good ... A little fight but was able to use the original paddle . do recall re drilling the Brake Pad to the right to accept the push rod

Did you use stock wheels with the Scarebird kit?

Anyone know if this setup works for a 1949 Olds 88? I'd like to keep the drum brakes but upgrade to power brakes with a vacuum booster.
Great work!!

i did use the stock wheels, but used a spacer adapter 5x5 2"
the 2" was what i had laying around ... im sure a 1 1/2 would be ok to use.
pic shown ...

Anyone got a pic of the difference between an OE wheel and the replacement for Discs?

Cheers.

I don’t have a photo but the offset of the oe wheels combined won’t clear the calipers.

Haven’t been here in a bit but I’m still here! Glad to see this project helped a few.

There should be a solution, at least for the rear, matching the OE 14" wheels:

Do you still have the '57 that you put this power brake booster configuration onto?
It looks as though the brake pedal pushes directly against the master cylinder push rod with NO mechanical multiplication (leverage). In other words a one-to-one brake pedal to master cylinder piston ratio.
How has it worked out? Do you seem to have normal brake "pedal" and function?
Thanks!
