John,
I remember that you have the Speedtech front clip on your car. I don't know what the width of the rear of their rail is but the adapter that we sell to fit the stock clip is 3-3/4" on the inside. The adapter slides over the outside of the stock rail and welds in place. Once that's done, the connectors bolt in place. It's $339 for the connectors and adapters. A bolt-in center support and driveshaft loop are also available. Click
HERE for details on the first gen kit.
Incidentally, the adapter fits first
and second gen Camaros.
