My rear lower control arm is now sitting on the ground on my 98 GT. Im looking for the bolt that connects it to the frame not the axel. I called all the Ford dealers in my area and they are wanting to charge me 20 bucks for a set of four bolts to hold it in. What grade and size are these bolts. I was going to pull the other side out but changed my mind after thinking about all of the extra work of pulling out the spring.
