I looked all over the internet and can't find info on 56 olds 88 brakes.If I buy this car I am looking at, without power brakes,can I convert it to power?A local yard has a few old olds so I can get parts,at least for the cores.Where can I get detailed plans on doing this? I have restored many cars starting in 77,but never did this job on this car before.Thanks for any info.
