Not Fairmont. That is a Fox chassis. Granada/Monarch/Versillies/Maverick/Comet all use same front brakes. They will swap straight over, but depending on your car, you may have to swap to larger tie rod ends. Ends are cheap though. 68-71 Fairlane/Torino/Cyclone/Montego 65-73 Mustang/Cougar Any Falcon Those discs will swap too. They are different than the later versions, and some vary year to year. The pre-68 stuff is complex and rare... It will fit though, so I listed it. Again, tie rod ends vary, and may need swapped to fit your car. Edit: Guess I should make it clear... The swap must include the spindles from the car that donates the brakes. You must get it ALL. You cannot just mount rotor and caliper to your drum spindles. Don't bother getting the tie rod ends. Those are cheap and it wouldn't be smart to get used ones. You may have known this, but I am just covering my bases.
http://www.discbrakeswap.com although his site is down for now... it's about 500 something for the conversion for our cars from him. with slotted rotors. about 615 with the swap 2 kit with upgraded rotors.
PM me. I Just pulled the spindles, rotors, calipers from a '77 Comet. I have everything you need except the lines (you'll need new ones anyway).
Yeah, he's got everything for the swap. It is repopped Granada stuff. It is real pricey considering you can go down to the junkyard and get a set for 50-100 bux. Even cheaper at a U-pull-it.
If you are looking for rear disk as well a 90's vintage Crown Vic's rear disk will fit 8" and small bearing 9" with minimal work.
I just did it to mine I just did it to my 72 LDO and with all new ball joints and tie rods It cost me about 400 the 100 bucks for the junkyard spindles is included in the 400. The only thing I noticed is nobody mentioned the proportioning valve for the brakes. I have noted that it is recommended to use the proportioning valve that came with the donor car so your rear brakes don't lock up before the front brakes. Also you might want to look at using a later model maverick master cylinder due to the fact that the resivoir is bigger for the front brakes.
About 6 months ago I bought a 74 grabber, 75 4dr and 73 comet 4dr for $200. The grabber has manual disc brabkes and the 75 4dr has power disc brakes. Around here you can find complete 4 dr cars with disc brakes for a few hundred dollars.
A company called Classic Tube has the brake lines. They are a bit pricey for a kit, but what value can you put on your safety?
This is the way to go. I bought the kit, every piece is there. I figure by the time you go to junk yards, buy the gas and the time it takes to get all the parts (time is money to me) it is better to buy the kit. JMO. Good luck. Also I thought the name of the company was CSPS.
