I am in the process of installing my 14" 6 piston kit #140-12638 on my 69. I am using factory drum spindles as recommended. The only way the kit will work and clear the spindle is for the caliper to mount towards the front of the vehicle. Every picture I see of a 69 or 70 with this same kit seems to show the opposite; the caliper mounts towards the rear of the vehicle. I spoke with Wilwood. He stated that all Mustangs of these years have rear mounted steering, and the caliper must be mounted towards the front of the car; opposite of the steering arm. I asked why all other 69/70's I have seen have the caliper mounted towards the rear and he was unsure.
The reason the kit I have will not work with the caliper mounted in the rear is the caliper bracket kits the steering arm/spindle. The guy at Wilwood verified that I have the right kit, but I am still concerned since every picture I find shows the opposite of my results. Can anyone shed some light on this for me?
This is the way every other 69 seems to have the calipers mounted. In this picture I would call that the 10:00 position. As you can see, the "C" shaped bracket on the left of the caliper bracket does not fit and the bottom 2 bolts attaching the C bracket to the caliper bracket will hit the spindle/steering arm.

This is the only way all bolts will light up without clearance issues on my car

These are pictures of all of the other 69/70 Mustangs I have found with either Wilwood or Baer 14" brakes with the caliper mounted towards the rear
