Topic: 69 shelby (June built) spindles

[cob428]

The more I read on spindles the more confused I become. On the Left side I have a KKX spindle, on the right side I have C80A. hen I see Bob Perkins has a C9ZZ Listed for the right side> trying to gt back to Concours and not sure what I should be using?

I believe you have what is referred to as “big suspension” with the larger F series tires.

There were two different spindles used the KKX and the DOZA B. The C8OA spindle would not be correct for a big suspension car.

Peter,
Can they be mixed for example a KKX and a DOZA or would they both be the same?
Would the one from Bob Perkins be correct for my car?
Thanks Pete

The C8OA is not for the larger suspension .It was used on 69 Shelby's prior to the big suspension being introduced.  It has smaller bearings and also designed for the smaller tie rod ends. The number you list for BP'S spindle is the Ford part number not to be confused with the engineering number which is physically on the spindle.The one BP has is for a Boss 302 or Shelby. As I mentioned to you in a PM some Boss 302 and 69/70 Shelby's cars came from the factory with a KKX cut down Boss spindle on one side and the DOZA-B on the other side. Not all but some. It was apparently a attempt to use up what they had first. As they are the same dimensions no harm no foul.

Are there any pics to illustrate the difference between the KKX and the other big  spindle?

Just for informational purposes, my April 14 car has the KKX spindles on both sides.

Not sure if there is a difference other than the markings between the early KKX and the "Big suspension" D0 versions that quickly followed

As for the difference between the regular and big suspension:
Other than the castings, a section of bailing wire wrapped around the upper part of the spindle as a quick identification for the line workers and paint marking differences it comes down the the difference in measurements of the bearing races - not something that would stand out if looking at one IMHO. There is a document posted in the 69 Library section concerning some screw ups on the line when the new suspension option was released concerning a group of cars where the parts (wrong rotors on the wrong spindles and so on)

Titled 69 Disc Brake Spindle and/or Hub and Rotor Mismatch Issue


Believe there are some close ups in the thread where I dissassembled the front suspension of my early 69 Boss did a little cleaning and reinstalled. Car has about 30K miles on it

I think a comparison of the KKX Boss 302/Shelby spindle and the KKX Boss 429 spindle is needed. I don't have any profile pictures of Boss 429 spindles to compare to. Ed can be challenged like me posting pictures sometimes so hopefully BP will have some to share . Hopefully Ed or BP will explain the difference between the KKX Boss 429 spindles and the KKX Boss 302 /post 3/69 Shelby spindles.

That looks to be the standard non heavy duty suspension spindle
