All 68 big blocks and some small blocks with special handling had the welded shock towers. The very late 68s had the wrap around style structure shock tower.
Here is a 68 J code GT that has the welded shock towers.

I have seen other regular 390 SJ Mustangs with the shock tower bracing weld like that however yours was probably added because it looks too nice like a mig welder. It doesn't really matter but I wonder if the lower spring plates were modified to clear the traction bars of the time that were bolted on the bottom side of the spring plates. I suspect this because the lower shock bolt hole is not a typical repair spot on the spring plates. There were clearance problems sometimes depending on brand. Like I said it doesn't really matter one way or the other because they are not stock regardless just a observation.

Thanks Bob. So just confirming that my lower shock plates are not stock. Do you have a photo of what a stock plate would look like

Thanks. Those look like mine. My car is a late May car. Good to know as someone told me that they did not come from the factory with the welds and they must have been welded by a previous owner. Glad I posted and asked the questions.
