Auto Body Specialties has a trunk extension that will work beautifully. It will need a small amount of trimming. I replaced a pair on my 67 Barracuda convertible.
Thanks for the tip, I see its the same Part number as a later dart/duster So as it states and you did you, minor trimming that'll work for me! Now to order these too. Oh and Im not going to mini tube, It had crossed my mind, but after seeing that I'd have to modify the interior pannels and on top of that I have to relize what the car will really be for, Just cruising around, I mean sure I want it to have a warmed over motor but the older Im getting and the longer ive had the car I just come to be more 'realistic' on the hole thing, But still wanna go 4 speed and pistol grip!
