No , NOT A Z 4 sure...
X-11 = Base model with Z21 Style trim pkg ... ( Included on SS350 model )
i guess it could be a SS350 .
I havent been able to really go over the car yet , STILL IN MY TRAILER ...
This is a "PROJECT CAR " and will take some work over time once i can get to it ...
I have a number of other builds going right now but i have it here when i do get time and its in line.
i think it will get a full NUT n BOLT rotisserie restoration ...Im excited about the car , Just want to find out as much as i can about the rarity before i decide what direction to go.
ITs a Factory SB / AUTO / car.. NO AIR....COSOLE CAR .
I havent checked the ralleys to see if they are originals or not yet.
Look forward to seeing some pictures of your project.
