Tips look awesome! What size are the outlets? 3.5" each? I picked up a set almost exactly like them, then got under the back-end and couldn't get those dang stockers off. Any tricks you'd like to share? I even took a sawzall to part and still couldn't get those old ones off. If you just did it in the driveway, did you just happen to get lucky and get a set that came off easily??
