mattskin

hey guys,
 
I'm Matthias from belgium and i just bought my first mustang so i'm a new rookie :) 
 
Now i was wondering how rare my mustang is because it's a fastback deluxe (63B) and i found on the internet that there where only 5958 produced of them ...
But my mustang also have the GT equipment and that's even more rare i think because of the low count GT equipment group?
 
I hope you guys can help me out with this so i actually know what car i'm restoring!
 
thanks a lot!!
