Can someone help regarding proper install for factory dual quad on my 401? None of my service manuals cover details of brackets, coil location etc. Was there a supplement service bulletin? I have or thought I had all the pieces but linkage to firewall and detente switch no fit? I’m attempting to be as factory correct as I can with my restoration. I heard a storey about dual quads on the 65 skylark, if u checked the box on dealer order for towing package, it came in the trunk and installed at dealer? True?
