I replaced my 16's with the RR 19's so I have a whole set but it seems before I got them someone did a job on some of mine. I had to tap a socket onto them just to get them off the truck. Let me look at them and I will let you know how many I have that are good, you are welcome to the others as well but I would just give them to you as I was going to throw the "bad" ones out anyway.
