I'm doing my homework now on which company I want to fetch a front disc conversion kit from for the '68 GTX. The kit I choose will have to work on my stock drum spindles.
GTX has 11" drums, front and rear of course.

I see on many kit descriptions saying they fit "stock 10" drum spindles".
Is there a difference in the 10" and 11" stock drum spindles?
 
As far as I know the spindles are the same. If you haven't already you may have to get 15" or larger wheels to clear the calipers. I just installed SSBC A156 on my '66 Charger and it was fairly easy to install.
 
I used the SSBC kit on both my cars. It uses the stock spindles. Kit was easy to install. The Cuda was done first using the 1 1/32" master cylinder that comes with the kit. I am less than impressed with stopping. Then changed the Belvedere to 15/16" master cylinder and stopping is way better. So, go with the smaller master cylinder.

I used a right stuff conversion I'd give it a B rating and it fit 15 wheels. It might fit 14s but might be tight depending on back spacing.

I used a Wilwood set from Jegs.
Cost was around $850 + $65 for a new set of Wilwood SS lines.
Conversion was fairly simple
 
When I researched this it came down to Dr Diff having the best solution. Yes you have to swap the knuckles, but it fits the 14 inch wheels.
I second the 15/16 master cylinder.
 
I did go with a manual 15/16 master cylinder, to avoid vacuum problems caused by a lumpy cam.
 
No difference,just referring to wheel diameter.With the race stuff the inside diameter of the rim must be checked.
 
As others have said, your first decision will have to be what size wheels you are going to run. I was planning to run 18s so I had a bunch of options to choose from.

There is a guy on DC.com that has developed brackets to mount 2005-2014 Ford Mustang discs and calipers using drum spindles and hubs. I went with the 13.2" fronts and a Wilwood 1 1/8" MC (I have power brakes) and couldn't be happier. Stopping power is amazing. $120 for brackets and $200 for take-off discs, calipers, pads, from ebay, plus new hoses and all done for under $400. You do need to do some very minor sanding (1/2mm) of the disc to fit flush on the hub, or others have had their hubs machined. A big plus for me was using quality OE parts that are easily sourced from any auto parts store, plus nearly unlimited options in brake discs or pad compounds.

i used the scarebird conversion plates. lets you use factory parts from other cars. super easy and cheep to put together. manual brakes will still almost lift you out of the seat when slamed.

@727- Did you install an adjustable prop valve? I have that SSBC kit for my 70 Satellite that I will be installing this winter.

The GTX has 15" Magnums, as can be seen in my pics on here, so that wasn't a worry.
I'm simply referring to the various kits' manufacturers' descriptions oftentimes reading "works with factory 10" drum spindles", yet not mentioning factory 11" drum spindles like many of these cars have (including mine).
I thought maybe the 10" drum spindles might be a different diameter?
Apparently not. Thanks to everyone who answered that! :)

I've got an email in to them right now. Their site shows a "budget" set of brackets for 14" wheels, but the description says they have a heavier duty option for cars with RB engines - yet there is no listing for one on the site that I can find.

P.S. That ssbc website is slower than death!
 
I did the Master Power purely because I didn't want to be restricted when I needed a replacement part. Everything is over the counter if you have a problem out on the road.
 
I also installed the Scarebird kit on my Charger last year. I tried to find some info on it, but it seems it may have gone out of production. It used to be "Product Code: BNE". Let us know what you hear from them. If they do still offer it, it's a good kit and fairly straight forward install with mostly off-the-shelf OEM parts (which is what i liked about it). The kit calls for rotors from a 70 Ford, calipers from a late model Dodge 1/2 ton truck, hoses from a Camaro, and a master cylinder from a '72 Cuda. Here's a quick rundown of prices:

-Scarebird Kit: $200 (after the tax and shipping)
-Rotors: $86 (Summit/$42.09 each)
Part#:BEN-PRT1016
-Calipers: $42 (Autozone/$20.99 each)
Part#: C554 (left)
Part#: C555 (right)
-Bearings: $25
-Master Cylinder: $26 (Autozone)
-Stainless Steel Russel Hoses: $42 (eBay)

The only thing left to buy are brake pads and you can spend anywhere from $20 for OEM replacements up to hundreds of dollars for extreme duty pads. So, realistically you're looking at around $500 after you factor in taxes, shipping, and a couple core costs if you don't have anything to turn in. Overall the kit was very easy to install and I'm happy with the performance too.

Edit: Here an idea of what's involved.
