It actually has been alot of fun piecing together this suspension and brakes-theres alot of stuff out there for the 59's but the challenge is to find it.
So heres my next question-any leads on a power booster/master cylinder set up for our cars? Everything Chevy looks like it wouldn't fit, but Jamco Suspension has a Cadillac setup that looks very close to a fit-I'll try to post a link-any thoughts or leads??

The set up I used was almost a direct bolt in. I used an 8" dual chamber master and booster off ebay. Bolt pattern matched, I was able to use heim joints on the rod to hook it to the pedal. I did have to notch the firewall slightly and flip the stock firewall bracket upside down. It was an easy swap

starchief,do you remember what make/model the booster assembly you bought was supposed to fit? I'll just get that one.
Canadianponcho, I bought an American Pontiac out of Mississippi-its kinda fun sourcing stuff for it up here in Canada

That is the one I got. It was a pretty easy swap. I can't comment on performance as my car is still just sitting. I did try to bleed the brakes multiple times and I still have no pedal. I'll pull it off again one day and bench bleed it again and put it all back together

Think this one might work? I'm going to need a proportioning valve.

If you're doing discs up front you will need a valve. That one would work.

You could try to find a different booster if you want. I need a small diameter one like that to fit my clutch master cylinder in there. The booster/Mc sticks out pretty far but I had to have it
