did I read your post wrong? You did say the frame was level at the motor mount right? and you said the fenders must be the issue. If so, why would you shim the spring pack? If the frame is level just bend the front fender suport to make the fenders level. That would still leave you a little low on the driver's rear fender, right? So measure the frame at the rear, if the same each side, check fender mounting and body mounts, if the frame is low on drivers side try all the same tricks you all ready tried on the front. On the body mounts, remember that the A had wood blocks between the body and frame. How well do your doors line up?
