Anyone know where to get an upper a-arm bump stop ? The polyurethane ones that are listed to work, won't. They are popped right out of the slot when the a-arms come down when the car is jacked up. Thanks. This is the front end a couple weeks ago before the motor was put in. As I mentioned in the thread where I needed pics of the vacuum lines, this car is getting a ground up resto. Everything looks this good. I even took a buffer and rubbing compound to the fan shroud.
