The '66-'67 big car disks use Kelsey-Hayes calipers, which are 4 piston and very wide, they actually used a special wheel
for these applications. '68&up use a floating, single piston caliper, and are much smaller.

hi roger
i finally realized that after seeing the difference on the tbird that i pulled the rims off of but do you know if the spindles on mine would work. if not what would be a good cheap or economical way car wise. i have heard of the 77-79 tbirds and cougars what would i need
thanks

I am not sure who the guy was that implanted 77-79 Ford, let me tell ya any 70's intermediate disc brake car will work. Mine are from a 76 Cougar however I also have a set of the larger ones 12" from a 70 Lincoln Cont that has the same bolt pattern 4.5 on 5 and will also fit the Galaxie. Your earlier selection of the 70's and late 60's have the Kelsey Hayes system but the ones that came on the mid to late 70's Fords and Merc's will work fine and they are cheap to get parts for.

This will give you more of a selection at the Bone Yard, don't forget that you will either have to run the 14" wheels off of a Ford/Merc car that had disc or 15" wheels. And look ford the tie rod ends to be in the Back of the spindles and while your out you will need to grab a good set of "Disc" tie rod ends (they will thread onto your center link) because of the lenth of the stocker they don't allow you to match up your king nut with the cotter key hole...

say what? i am not sure what you are trying to get across exactly......but, i personally used outer tie rod ends from a 1970 ltd on my 67 galaxie brake conversion. the tie rod from the donor car wouldn't fit in the sleeve. tip number 2: 2 outer tie rod ends from autozone 23.98 + tax a pair and made in america. everywhere else wanted 35.00+ a piece.

That's right, the tie rod ends from the 70's intermediates will not work with the early galaxie tie rod (different diameter threaded section). I can confirm from experience that they will not.

The cars you should look for are 77-79 Tbirds. You can also use parts from Montegos, Rancheros, Elite, LTDII, Torino, Cougar, etc but I don't know the exact year spread of those models.

You'll change the spindle and everything outboard of it. Your factory spindle will not work with the later model disc setup. You also will want to change to a dual reservoir master cylinder.

Change it now. You are going to have to fabricate new hard lines when you swap the new brakes in anyway, so just do it all at once. Plus the dual master is MUCH safer.
