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

Purely speculating, but aftermarket spindles with different steering arms possibly? Although, you would expect to see a mix of both in photos.

This is a 66, but shows them on the front

Maybe you've got 65 spindles? You can swap the disc spindles back and forth so I'd imagine drums could do the same, I'd expect the drum versions would also have the steering arm differences that the disc spindles do.

I have already confirmed with Wilwood that I have the correct parts

So the spindles came with the kit? Or do you mean they verified that you had the correct spindle?

The kit is for a factory drum spindle for a 69 Mustang. I took these spindles directly off of a factory drum car, and have 2 other drum 69 Mustangs that I was able to look at for reference to confirm that the spindles are correct for a 69 drum car

Make sure that the pictures your looking at for reference are using a stock drum spindle. One of the pictures you posted is cts-v fastback that is DSE equipped and uses a corvette spindle. Two of the other pictures show the Ridetech fastback which could be using their spindle design or an aftermarket spindle. Do also keep in mind the 68/69 spindle is different then a 1970 "big bearing" spindle which is a very common upgrade and may have a slightly different steering arm.

My suggestion would be to contact Steve at east bay muscle cars and ask about his burgundy mustang you posted maybe he can shed some light.

Also hit up Bret Vokel at Ridetech and pic his brain on their spindle brake setup on the silver car

With so many different spindle options on the market try not to read too far into pictures you see without knowing the specific setup. Hope the above info helps.
