SSBC makes a bolt in 4 lug disk brake kit.  It is designed for the 13" brakes, so the rotor is none too large - maybe 10", but that was the original size of the MII brakes.  One other consideration is to install 65-66 spindles.  Then the suspension/steering geometry is proper, but you may have to do something to your ball joints and steering linkage.

I think you meant 13" WHEELS?, not brakes.
Also, installing 65/66 V8 spindles on 65/66 I-6 steering linkage also produces some pretty wild steering geometry, albeint not as bad as if the Granada spindles are used. 
Best solution is 65/66 V8 spindles with 65/66 V8 steering linkage.  Then you can choose from the stock factory Kelsey Hayes 11" discs or an upgrade to 11.2" 05-2010 V6 brakes or 12.5" or 13.2" GT disc brakes.  The 11" KH brakes will work with 14" wheels.  The 11.2" V-6 brakes from 05 or later have to have a 16" wheel.
 

Changing to 65/66 V8 spindles with V8 steering linkage will get it right.  Even the 65/66 V8 spindles, if used with the six cyinder steering parts will have severe bumpsteer.
I recently picked up a V8 manual centerlink and tie rods with adjusters that could sell cheap.  You still need V8 pitman and idler arms. 

Thanks alot guys the help and advice are much appreciated! I've gotten myself into a bit of a quagmire here and unfortunately went off half cocked and spent money on some parts that I may not be able to use My latest project is a 1963 Falcon , back when I was building Mustangs and other "falcon" chassis cars 20 years ago the 70's disc spindle was a state of the art upgrade but alot has changed since then. Unfortunately I made a rookie mistake and snapped up a complete steering and brake system from a '76 Maverick thinking A) they allow me to upgrade to p/s B) the disc spindles were an instant bolt on improvement. now I'm not so sure about the spindles   lowercase: i'm converting to 5 lug, MS: thanks again for the clarification and the benefit of your experience and knowledge I hadnt realised even the 6 steering and V8 spindles would cause problems one thing I've learned in 35 years of messing with these cars is that if you assume a part will interchange it won't! I guess your talking about '65-6 V8 disc spindles? they would be hard to find and probably expensive or are the spindles the same? Mcstang thanks for the generous offer same question to you are they drum or disc? MS as far as I know there were no V8 disc falcon spindles if so theyre probably rare as hens teeth barnett: thanks for the links that seems like the best option for using the stock 4 lug spindle I have managed to compare a '65 Falcon V8 p/s system now the question is if the 6 steering and V8 drum spindles don't work together, the 6 steering w adapter sleeves and maverick spindles don't work, what would be the result of using the V8 steering with the 6 cyl. spindles? do the tie rod ends fit? and will this combo maintain the correct '63 ackerman angle? or does use of the V8 pitman and idler change that too? - Thanks

lol been there done that a '66 and two '68 coupes, one (bolt on reflectors) 289 with special order paint and blank code 1 of only 3 known in that color all original except 4v man. the other '68 I put the C code in the '66 and installed a '69 351W mach 1 engine and toploader, lincoln disc brk 9", and granada spindles, steve mcqueen green.......point is in those days they all sold in the under 3 grand range now you cant even lay your hands on a basket case for that falcons are cheap and and i'm on a low budget

I would love to build a nice '63 Falcon - fond of this one:

Mcstang yeah that is a cool car especially the history.....  so what type of spindles do you have drum or disc?
MS I'll put this question out there again: is it possible to put 5 lug hubs on the 4 lug spindles? and this one: will the '65 V8 falcon tie rod ends and steering linkage work with the 6 cyl spindles? so that I can use a disc conversion instead of the maverick spindles I know its an O/T car but I turn to you guys because alot of the mods I want to do are typical mustang stuff

CJPony had a sety of 4 lug front discs on their closeout list today.  Just under $800   OUCH!

I believe the Falcon spindles are same as Mustang. The Maverick is like a Granada with the same bumpsteer issues.

I had looked at coming out with a 4 lug kit for early Mustangs, but I just don't think the demand is there for it to ever make any money.  Especially if it involves keeping that anemic 4-lug rear end that will eventually fail and not be repairable.  For a six cylinder owner that is planning on keeping his car for a long time, the 8" rear and V8 steering/spindles conversion from a 65/66 Mustang just makes the most sense to me.  It opens up a world of wheel/tire options that do not exist for the four lug stuff.

I do have spindles available that would allow you to use the Maverick discs on a spindle with the correct geometry for an early car like yours. But, they are V8 geometry and would require the V8 steering components to work.

I agree but did stumble on this post at VMF from Dennis of CSRP about a kit he's developing to put K/H brakes on 6-cyl cars without changing the linkage. Not exactly wha the OP is looking for and I'm not sure of the compatibility with the '63 Falcon six linkage but here it is:
