You want the kit for the 70-73 Mustangs as the Granada spindles use the same taper. As a side note, I had to trim about 1/2" off the adjusting sleeves to properly set the toe.
2bav8 how do you like the Baer bump steer kit? I asked about it recently on Ultrastang's Granada spindle/Cobra brakes conversion thread, and noone seemed to have any experience with the kit with Granada spindles.
Ditto what 2bav8 said. I've got the Granada spindles on my '65 and have the '70 Baer Bumpsteer kit on. I, also, had to trim off the adjustment sleeves to get the proper alignment.
I had the Pro-Motorsports bumpsteer kit on with my original spindles prior to this set up and swapping to the Baer kit really helped to reduce the steering effort on my car.
For your initial setting, add and/or subtract shims until you get your Tie Rods parallel to your lower control arms. Then go for your alignment and recheck for parallel. This is probably going to be your ideal setting, but you can play with moving the shims from there.
The Performance alignment settings are:
Caster: +2.5°
Camber: 0 to -.5°
Toe: 1/8"
