Topic: 67 Running Changes Main Thread - Metuchen/NJ Findings

[J_Speegle]

So here is another Running Changes thread this time focused on 67 Metuchen Mustangs. We'll follow the same post, discuss  (if need be if it belongs), add to the list, then delete the suggestion to keep the thread compact and up to date as much as possible.  So post what you understand was affected by running changes and I'll keep an ongoing list here in the first post. Some of these will likely match other plants fairly close and some items will list the dates from the TSB and other supporting documents also as we have elsewhere.  From there we'll collect data, assemble the first report and see how it works.

To keep the thread from getting too long or out of hand please don't post that you found this version or that on car 7T02C2345xx (for example). We can save that for the research period and for the individual change threads. Just trying to identify the features during this first effort. Will break out the findings by plant of course.  Hope we can work through other plants also.

Many of these running changes will be shared with the other two plants while others were possibly done on different days due to difference in supply, inventory or other issues.

       also link the other two plant running change threads once established.
