You considered the following and you said you wanted a finished hood trunk and doors.
Lone Star
Mid-States
RUCC
B&B Manufaturing
Shell Valley
Factory Five
All except the Factory Five have the finished insides on the hood and trunk. If you want a IRS suspension That eliminates all your list except Midstates and Shell Valley and FFR if you forget the liners. I wanted IRS and a lined hood and trunk so I was intrigued by Hunters kit. It has the hand laid body with fully lined hood trunk and doors. The suspension is based on a C4 corvette which is aluminum and IRS. It has a aluminum fuel tank, front and rear sway bars, 16gauge steel floor and can accomidate any motor you want. Randy has even built some with viper motors. The Rolling chassis Kit with the corvette suspension is $10,100 for a 90inch wb or $10,600 for 96inch wb.
If you want to look at one I live near Pensacola and there are several cars in this area from Uniques, FFR, Classic roadsters etc.
If you want to see several cobras in action we are holding a track day next weekend in Gainesville and you are welcome to ride with me from here next friday. We also have the reptile roundup in November and there will be from 40 to 60 cars there.
