I have a 87 mustang 5.0. It has T-tops. It is a true 5.0 Not a swap job. How can I tell if it is a GT or a LX. What number or letter on my VIN can I look at to see if its a GT or a LX. I am just curious about it. I have heard that LX T-top stangs are hard to find. Someone here should know or can point me in the right direction.
