Converting Power Front Drums to Discs
I'm planning on converting my power front drum brakes to discs on my 1971 Olds Cutlass Supreme convertible. Do I require a new booster as in some kits or can I save some money and get a kit without one?

There are some attractively priced kits available that include everything needed for your conversion---including a booster. The cheaper kits are mostly parts made outside the good old U.S.A. and are fine for most builds. If you are going to be showing for points, these kits will not be for you. Also, most (not all) of the advertised "complete" kits use a larger caliper that won't clear 14" wheels.

The best deal found up here is $649 plus about $100 shipping. No free shipping via UPS up here . They bend us over freight wise anytime they can .
I have 15" American Racing wheels on the car, can't see any problem with clearance.

I have used the kit for a 4 wheel conversion from getdiscbrakes dot com, the fronts fit a 14 inch wheel , the rears rub because of the mounting brackets I used the new spindles but used my steering arms, I also got bit by the maw monster and added stainless lines, stainless flex, 9 inch booster, moved the proportioning valve under the master cylinder to allow better exhaust clearances and slotted and drilled rotor as well as powder coated calipers , it isn't cheap but the kit was great. I give it two wrenches up
. The base kit is much cheaper and they do make a factory 14 inch kit, remember it is getting to be a biotech to find 14 and 15 inch performance rwl tires at least for me
so u might want to go to 15's at least

Check out www.scarebird.com A proportioning valve is only for adjusting the pressure to the rear brakes to insure which ( front or back ) locks up first.

Well, considering that drum brake cars DON'T USE a prop valve, yeah, they're "different". Again, not the question the OP asked...
A-body disc brake conversions are trivially easy. I suggest reading this thread:
