Jack's Comments:

This decal was on all Mustangs and Shelby's in different locations depending on factory and engine option. Examples would include the top firewall area on the passenger side (common BOSS 429), the driver side shock tower, the passenger side shock tower, or the driver side inner fender well next to the washer bottle. See pictures below showing locations on some cars we have documented.

All we know is the cut-over date to the newer 1970 version was early in 1970 production. It would be safe to assume that if your car was produced in the first few months of 1970 production this decal would be correct for your car. Sorry, no exact cut-over date is known.

Update: We have documented a few verified original cars below that might help with the 1970 cut-over date.
