Here's a Thule T2 add-on that I have. The stinger piece is new (used once) from e-trailer and I added the trays. They have N183 lock cores in them but I don't have the keys. I pieced it together thinking I'd be hauling around more bikes but 9 times out of 10 I only have one on the rack. Would love to see it be used by some kids on bikes! Make me an offer if you're interested. I'm located in Somerville, NJ
