65 Valiant

I picked up the last car of 4 I bought this spring. The car is a Signet V-8/ auto, convertible. It has no motor or trans. As I was loading it I noticed it had a 5-6" notch made into the rear valance on the drivers side. I looked it over and it is factory made into the valance and has a bracket mount on the frame rail. All the other V-8 cars do not have
this notch. Could this indicate a resonator exhaust was factory on this car and what option packages could you get this in? I inspected the valance and it is factory installed and has no indications of ever being welded on as a replacement. The inner fender tag is missing and I am hoping it is in with all the parts buckets I got with the car. There are no rear seats so no build sheet. Please help.

your vert is indeed a commando car, and requires the resonator with the large stainless tip, which fills in that cut out notch very nicely. Accurate exhaust systems in oregon sells a complete factory style exhaust system, including the resonator. google them for pics and info. many of those cars came without a sway bar. your lower control arms have the sway bar link tabs on them, so its easy to obtain a factory sway bar and bolt it in. I have 3 65 valiant converts and 1 65 barracuda commando cars, and am a certified early valiant nut/enthusiast. let me know if you need any help sourcing parts or have any other questions about your 65.
