The trans mount looks like there wasn't a lot of modification from original but it is hard to tell from the photo. I tried to find the original ad and the pictures so we could take a better look at what they did but could not find it. If I stumble onto it I'll post the pics. The Mustang Forums are giving the AJE tubular mounts good reviews. One guy has had the system in for 6 years trouble free. I was always suspect of the way it attaches to the original "frame" of the car. It looks a little "hokey" from the pictures but when you work in a welding and fab shop bolt on stuff often does.
