Topic: 69 shelby (June built) spindles

Your tie rods will have the smaller shaft on the C8 side too.

The spindle was most likely changed out when the rotor needed to be replaced. The correct Boss 302/post 3/69 Shelby rotor has always been difficult to find. Most mechanics if they cant find the correct rotor would simply change out the spindle . Seldom if ever do they think outside box and take the rotor hat off of a 70 rotor assembly and transfer it to the original hub to solve the problem.

Thats my next project, pull the tie rods off to check and see what is going on. I do know 3 of the 4 have zerks so they have been changed , the inner drivers side appears to be original. Is there an easy way to tell?

First off the tie rods will not have grease zerts. You should check out the article Marcus did .The link is in the library.The nut size is larger on the big suspension tie rods compared to the small suspension. The tie rod shaft is larger. So the castle nut will be larger too holding the tie rod secure .That is a easy tell from the underside.  On a big suspension the drag link will be different in that it accepts the larger tie rod shaft. In your case the outer tie rod on the side with the C8 spindle will have had to be changed to the smaller version so that it will fit the smaller suspension C8 spindle.

I have heard of another 69 big suspension Shelby that had same spindles that u have and they have F-60-15 bigger bearing rotors I was told. Ford may have used some c8oa spindles that were machined for the F-60-15 boss 302 Shelby rotors. The kkx boss 429 spindles were longer that the double wire wrapped ID boss 302 Shelby spindles. The spindles rotors tie rods drag link strut rods upper a arms were all different beefed up parts to work with the new F-60-15 tires. Check the tierod stud and nut hole and the bearing size on the c8oa spindles first compared to the kkx spindle on your other side first to see exactly what u have and compare both rotors to see if they match the same.

cob428  did the c8oa spindle have the double wire wrap on it?

[cob428]

There is a wire wrap on it but I haven't pulled it apart yet.

I'd like to see a pic of the wire wrap.

Ok, guilty of not seeing any of those posts!
Sometimes I start viewing a few posts in the shop and then return inside. The forum thinks I've read the post, when I haven't.
That's my excuse and I'm sticking to it!

Ok both spindles have 2 wire wraps on them , the C80A spindle (passenger side) has a build date of 9D21, the KKX spindle has a build date of 8J24 took both rotors off and bearings out, they are exactly the same. The inside drivers side tie rod is original and fits in both spindles without any issues. Did they make a big spindled C80A spindle?

............... Did they make a big spindled C80A spindle?

That has not been the understanding for years but with a number of discussions going on currently online and off on this and another site there appears to be some new understandings forming (from my observations).

Are the dates you posted from  the cars the spindles came off of? Just trying to understand the context

Re read reply #19 and follow his directions. In a nutshell if the bearings are the same and it has the larger same size hole for the tie rod like your other side then you may have a match.

I have some unmachined spindles out of KK plant and I think for (at that time anyway) ford machined kkx, doza-b or c8oa what ever they had cast and machined them according to the order of bearing size to fit rotors. I have seen many 69 big suspension shelbys with mismatched ID on the spindles but they always have the double wire wrapped around top of them to ID them AND I am not talking about the 2 safety wires going thru the caliper mounting bracket bolt hollow holes that tie it to the spindles as the wire I am talking about serves no purpose but to ID spindle  on assembly line.
