Topic: San Jose tie rod adjusting sleeves question

[69supercj]

Working on the steering on the SCJ and was detailing the adjusting sleeves and noticed that mine had lock washers and according to what I've read they should have locknuts. So I went to my parts stash and found a couple sets of tie rods and they both had locknuts so I'm gonna swap them out. My question though is the bolt. Mine had fine threads with a RSC stamped into 3 of them and the fourth one had an A. Same with the others except that they were a coarse thread. Any idea as to what would be correct?

Unfortunately the only relevant picture I have from the 3/69 built SJ SCJ car I had is from the wrong side     Looks like a TR head marking on the bolt though.

Would normally start out with when the car was completed now that you provided where it was built but see from you very first post on the site that you have a Feb 69 built San Jose Mustang. Is that correct?

Looking through my pictures I on;y found, at this point, the locking nuts versions. Not to say that there was not a second supplier that used the washers but that secondary supplier may have provided a much smaller percentage of parts compared to the self locking version and its tough to prove things at this point without more examples from the same time period since the supply would be date focused IMHO. Kind of focused on the Jan - April 1969 period for this discussion as far as pictures


Jan completed examples with self locking nuts








Eamples from April (likely) built cars







As for head markings, sorry these were not cleaned and made fresh but you can make out the three lines at least in this example from Jan 69

Yes Jeff its a Feb.14th built car. I believe the RSC and A markings to be correct just because of the simple fact that I've got 3 different sets of adjusting sleeves from various cars parted out over the years and they have the same markings on them. Would be too much of a coincidence otherwise I would think. And 2 sets were fine thread and one was coarse thread.

So you have only parted out 69's from San Jose or could these be from other years, plants or time periods.

You have to make the best choice for your project. I can only offer what I've found and can document.

I have no idea as to the assembly plants on the cars I've parted. Have you seen both fine and coarse threads on these by chance?

Different years and plants though vast majority have been fine. In addition to other details

Of course there is a mix of aftermarket, replacements and NOS/Service parts that get mixed in any searches that is why we look for multiples and hold the orphans at arms length. Standard practice has evolved to a minimum of three examples from same plant and production period just to have some standard

Thank you for trying to help however I would submit that if unless you can not provide a picture that can show if fine threads or course and or the head markings that and in the context of the OP's question - you are wasting your time. At least it shows a alternative lock nut.

The picture above is another confirmation of the style of nut used (self locking) was was mentioned in the original posting. So its at least another data point on that detail.

For 1969 should be coarse thread....I dont think you see original cars with fine thread anymore at this point.  Hardware in question I have detailed here on page 36 - click the link:

Amazing work on the detail writeups on the suspension parts Marcus!  I looked over the glass etching and hold down brackets as well.  Do you need more quarter glass samples for the 1969?  My glass is like the 67-68 style, but it is dated 8H.

Thanks Dave.  Im good on the glass etching samples and information I put together for now.
