Our 67 coupe is still on a rotisserie, I'm wondering, do I need to provide the exhaust system to the restoration shop so exhaust hangers can be installed prior to sealing up the undercarriage? Wasn't sure if the exhaust hangers are welded or bolted in place. Unsure what exhaust I want to use at this time. 289 with long tube headers is really about all I know for now. The rear valance is a non-GT, so will probably install turn down tips on the dual exhaust system. Thanks!
