I have yet to find anything here like this,so hope not being redundant.
I am upgrading single to double circuit master cylinder, no brainer on that part. Car has the accordion brake booster, and does work properly,but wondering if newer style would interchange since master cylinder studs mounted in firewall, and booster is mounted above.
But, found a post/thing on interweb about upgrading front to disk. I am posting some of what was said, and wondering if any have done, or know of if will interchange. Thanks in advance for any advice.

What I found-however, any fifth avenue, diplomat, etc will work. i have a similarly equipped sedan and the brakes were rough to say the least, so i opted just to up-grade. the donor car i picked up for $100 was an '89 police diplomat (11" discs, 11" drums). wheels i used were the 15" off of the '89. the spindles were an exact fit, some mix-matching on the tie-rod ends and it still needs some alignment done but for the most part easy bolt-in. same ball joints, the tie-rod ends r slightly different on the bolt portion, but is only hight, diameter is same. removed non-power assist of and plate behind it on '59 and used the donor car. still working out minor kinks. removed original studs, new p/b fit perfect. on the inside could only access 3 out of 4 studs to install nuts,

The F body front brakes will interchange with some B & all E bodies. I believe J & M body brakes are the same as F body. I too was looking for a front disc conversion for my 59 Imperial and had thought about the F body stuff as a donor. I haven't tried to fit them yet but the spindle heights are way different, not sure what other dimensions are incompatible too.
Scarebird has some conversion kits for other models, he says the 59's are on their list to work on.
