Testimonial: Late model helped build two of my mustangs
I have had a bunch of different mustangs in the past and always was hard to get parts till a friend told me about Late model restoration when I had my 1993 cobra and I found everything I needed to finish that car and am now working on my 1986 gt and am finding everything I need . I had a transmission mount delivered to me without the mounting bolts and they more than made up the difference for the missing bolts ! Out of all the parts I have ordered one mistake ever was very well taken care of . I definitely will plan on finishing my 86 gt with the help of Late model restoration ! Thanks !
