...................... Notice in the picture the hose adapter not riveted to the inside of wheel house rather pushed through the outside (prior scoop install) and riveted in. Never seen that either!
Yes and so should the duct in the rear wheel well be installed from the outside of the car rather than from the inside like earlier cars. After all the cars built the other way the change may have been changed for some unknown reason - easier or change of worker assigned to that task
You will see and read allot of things. Not all will be correct and stories told for decades get retold and retold on the web.
if someone has seen these rivets before or can source them --let me know. .....
May have been a change in tool or rivet not certain - just a possibility IMHO
Here are some examples of what appears to be the change. Looks like the two changes (direction the ducts installed) and the rivet change may have taken place at or around the same time. Haven't gone through all my pictures and data to graph out the findings and post a survey finding as I've done with other details
