Just another suggested running change survey. So show us what you've found and documented. Still starting out with San Jose only examples.
This time its the routing of the brake lines from the distribution block to the center of the firewall. Two routes have been documented.
One with both lines routed above the steering column (at firewall) location as shown below.
The second with both lines routed below the steering column location as shown below. Yes there is a non-factory wire existing the hole for the throttle for some reason
Have some examples samples but can always use more - your may be in the change over gap that always seems to come up. Real build/finish dates are important and at least a partial (for spread sheet ordering) is important.

Using the information submitted and my data base its pretty clear IMHO. I tracked which examples appeared to have been altered, restored, modified or upgraded (new brake lines) ignored them if they were orphans - single examples months from other similar findings. Have a handful of cars built just before April 28th that were unrestored with the over the steering column routing and about a half a dozen completed on May 1st with the under the steering column routing. Have a couple of under style around the same time period but don't have real dates for those. Have one example with a VIN that might be from between those two dates or no and since I don't have a real date on that example it was not considered but think only a four day window is pretty good given the amount of time that has past.
The routing is not IMHO related to any other feature or change. Findings were consistent with 6 cylinders as they were with all V8's. Solid or "rag joint" column configurations did not change the pattern either. Hope this helps others
